Clinton Peoples was born in Bridgeport, Texas on 25th August, 1910. He served as deputy sheriff in Conroe. Later Governor Miriam Ferguson appointed him as a special investigator of the state's four horse racing tracks.
In 1941 Peoples joined the Texas Department of Public Safety as a highway patrolman. Following the end of the Second World War Peoples joined the Texas Rangers in Austin. Peoples concentrated on political corruption and investigated the activities of George Parr.
In 1960 Henry Marshall was asked to investigate the activities of Billie Sol Estes. Marshall discovered that over a two year period, Estes had purchased 3,200 acres of cotton allotments from 116 different farmers. Marshall wrote to his superiors in Washington on 31st August, 1960, that: "The regulations should be strengthened to support our disapproval of every case (of allotment transfers)".
When he heard the news, Billie Sol Estes sent his lawyer, John P. Dennison, to meet Marshall in Robertson County. At the meeting on 17th January, 1961, Marshall told Dennison that Estes was clearly involved in a "scheme or device to buy allotments, and will not be approved, and prosecution will follow if this operation is ever used."
Marshall was disturbed that as a result of sending a report of his meeting to Washington, he was offered a new post at headquarters. He assumed that Billie Sol Estes had friends in high places and that they wanted him removed from the field office in Robertson County. Marshall refused what he considered to be a bribe.
A week after the meeting between Marshall and Dennison, A. B. Foster, manager of Billie Sol Enterprises, wrote to Clifton C. Carter, a close aide to Lyndon B. Johnson, telling him about the problems that Marshall was causing the company. Foster wrote that "we would sincerely appreciate your investigating this and seeing if anything can be done."
Over the next few months Marshall had meetings with eleven county committees in Texas. He pointed out that Billie Sol Estes scheme to buy cotton allotments were illegal. This information was then communicated to those farmers who had been sold their cotton allotments to Billie Sol Enterprises.
On 3rd June, 1961, Henry Marshall was found dead on his farm by the side of his Chevy Fleetside pickup truck. His rifle lay beside him. He had been shot five times with his own rifle. County Sheriff Howard Stegall decreed that Marshall had committed suicide. No pictures were taken of the crime scene, no blood samples were taken of the stains on the truck (the truck was washed and waxed the following day), and no check for fingerprints were made on the rifle or pickup.
Marshall's wife (Sybil Marshall) and brother (Robert Marshall) refused to believe he had committed suicide and posted a $2,000 reward for information leading to a murder conviction. The undertaker, Manley Jones, also reported: "To me it looked like murder. I just do not believe a man could shoot himself like that." The undertaker's son, Raymond Jones, later told the journalist, Bill Adler in 1986: "Daddy said he told Judge Farmer there was no way Mr. Marshall could have killed himself. Daddy had seen suicides before. JPs depend on us and our judgments about such things. we see a lot more deaths than they do. But in this case, Daddy said, Judge Farmer told him he was going to put suicide on the death certificate because the sheriff told him to." As a result, Lee Farmer returned a suicide verdict: "death by gunshot, self-inflicted."
Sybil Marshall hired an attorney, W. S. Barron, in order to persuade the Robertson County authorities to change the ruling on Marshall's cause of death.
One man who did believe that Marshall had been murdered was Clint Peoples. He had reported to Colonel Homer Garrison, director of the Texas Department of Public Safety, that it "would have been utterly impossible for Mr. Marshall to have taken his own life."
Peoples also interviewed Nolan Griffin, a gas station attendant in Robertson County. Griffin claimed that on the day of Marshall's death, he had been asked by a stranger for directions to Marshall's farm. A Texas Ranger artist, Thadd Johnson, drew a facial sketch based on a description given by Griffin. Peoples eventually came to the conclusion that this man was Mac Wallace, the convicted murderer of John Kinser.
Peoples gained a reputation as someone who was incorruptible and in 1969 was promoted to Senior Ranger Captain for the Texas Rangers. He retired from the force in March, 1974. Soon afterwards President Richard Nixon appointed Peoples as U.S. Marshall for the Northern District of Texas.
After retiring Peoples continued to investigate the murder of Henry Marshall. In 1979 he interviewed Billy Sol Estes in prison. Estes promised that "when he was released he would solve the puzzle of Henry Marshall's death".
Billie Sol Estes was released from prison in December, 1983. Three months later he appeared before the Robertson County grand jury. He confessed that Henry Marshall was murdered because it was feared he would "blow the whistle" on the cotton allotment scam. Billie Sol Estes claimed that Marshall was murdered on the orders of Lyndon B. Johnson, who was afraid that his own role in this scam would become public knowledge. According to Estes, Clifton C. Carter, Johnson's long-term aide, had ordered Marshall to approve 138 cotton allotment transfers.
Billie Sol Estes told the grand jury that he had a meeting with Johnson and Carter about Henry Marshall. Johnson suggested that Marshall be promoted out of Texas. Estes agreed and replied: "Let's transfer him, let's get him out of here. Get him a better job, make him an assistant secretary of agriculture." However, Marshall rejected the idea of being promoted in order to keep him quiet.
Estes, Johnson and Carter had another meeting on 17th January, 1961, to discuss what to do about Henry Marshall. Also at the meeting was Mac Wallace. After it was pointed out that Marshall had refused promotion to Washington, Johnson said: "It looks like we'll just have to get rid of him." Wallace, who Estes described as a hitman, was given the assignment.
Billie Sol Estes also told the grand jury that he met Clifton C. Carter and Mac Wallace at his home in Pecos after Marshall was killed. Wallace described how he waited for Marshall at his farm. He planned to kill him and make it appear as if Marshall committed suicide by carbon monoxide poisoning. However, Marshall fought back and he was forced to shoot him with his own rifle. He quoted Carter as saying that Wallace "sure did botch it up." Johnson was now forced to use his influence to get the authorities in Texas to cover-up the murder.
The grand jury rejected the testimony of Billie Sol Estes. Carter, Wallace and Johnson were all dead and could not confirm Billie Sol's testimony. However, the Grand Jury did change the verdict on the death of Henry Marshall from suicide to death by gunshot.
On 9th August, 1984, Estes' lawyer, Douglas Caddy, wrote to Stephen S. Trott at the U.S. Department of Justice. In the letter Caddy claimed that Estes, Lyndon B. Johnson, Mac Wallace and Clifton C. Carter had been involved in the murders of Henry Marshall, George Krutilek, Harold Orr, Ike Rogers, Coleman Wade, Josefa Johnson, John Kinser and John F. Kennedy. Caddy added: "Mr. Estes is willing to testify that LBJ ordered these killings, and that he transmitted his orders through Cliff Carter to Mac Wallace, who executed the murders."
Four days later, the Texas Bureau of Vital Statistics ruled that there was now "clear and convincing" evidence to prove Henry Marshall was murdered and State District Judge Peter Lowry ordered that the death certificate should be changed to "homicide by gunshot wounds".
Clinton Peoples was killed in an automobile accident on 22nd June, 1992.
In Washington, the House Intergovernmental Relations subcommittee was holding hearings on Billie Sol's cotton allotments. Among those testifying was Carl J. Miller, the Agriculture Department official responsible for allowing the Estes grain storage bond to remain at $700,000 instead of raising it to $1 million. Miller said he'd been visited by Estes, who mentioned names of the politically powerful to whom he was connected.
Meanwhile, the Robertson County grand jury heard testimony from a Hearne gas station attendant named Nolan Griffin, who said that reading about the case in the newspapers had reminded him of a fellow who stopped by the station to ask directions around the time Marshall died, a year earlier. The man asked Griffin where the county seat was and then he asked where "the Marshall place" was, Griffin told the grand jury. The following day, the man returned to the station and told Griffin, "You gave me the wrong Marshall, but that's all right. I got my deer lease."
Griffin said the man drove a 1958 or '59 Plymouth or Dodge station wagon. He said the man wore dark-rimmed glasses, had dark hair and a scarred, dark face. A Texas Ranger artist, Thadd Johnson, drew a facial sketch of the fellow, dubbed "Mr. X," which was circulated in newspapers across the state and country.
By the middle of August, the police had a lead in West Texas. On August 21, Texas Ranger Captain Clint Peoples flew with Griffin to Odessa, where a man said to resemble the composite drawing was interrogated by Peoples and positively identified by Griffin, according to a sworn statement Griffin made the fallowing week. The lead, howe~er, proved unfounded: the man, whose name was not released and has since been lost to time, was "checked out and completely cleared" by the Rangers after passing a polygraph test.
A few days after Griffin returned home, he received an eerie, anonymous phone call warning him to keep an eye on his children and to watch what he said, Griffin recalled recently. Shortly after that, Griffin said, Hearne Police Chief Perkins visited him at work one morning and told him Bryan Russ, the county attorney, wanted to see him right away. Griffin waited for his boss to return and rushed over to Russ's office, where he found Russ sitting with Sheriff Howard Stegall.
"While I was talking to Howard," Griffin, now a Hearne city councilman, told the Observer, "he handed me a pen and Bryan shoved a paper under me and asked me to sign it. I didn't know what it was, didn't read it or anything. They were my friends and I just did what they asked me to. A minute or so later, they got up, shook my hand, and I left."
What Griffin did, he now says, was unwittingly sign an affidavit stating that he positively identified the Odessa man on August 21, 1962. This meant, of course, that the testimony he gave the grand jury was effectively discredited, giving added weight to the local authorities and to the FBI's suicide theory. "I never positively identified the man. All I did was sign my name when they shoved the thing under me." The affidavit states: "I told the Rangers on that day that this was the man and I knew it on that date and I know it now. I cannot identify any other person for I am positive that this is the man."
Bryan Russ is now in private practice in Hearne after nearly a quarter-century as county attorney. Russ said he "doesn't even remember him (Griffin) signing anything. That's 20 some odd years ago. I have no recollection at this point. "
Over the years Clint Peoples has become an expert in homicide investigation. He has worked hard at understanding the processes by which one undertakes to scientifically gather and sift evidence leading to solving a murder case. There is some intuition involved in each case, but mostly it is just hard work. And it is with the hard work in mind that Peoples states that he has missed on "very, very few" murder cases in his half century in law enforcement. But according to his wife, the most perplexed he ever was on an investigation of any sort was the
Henry H. Marshall case. "I'll go to my grave knowing Henry Marshall was murdered," Peoples says in acknowledging this, his most puzzling investigation, one of the "very, very few" he has not been able to solve.
Henry Marshall, age fifty-one, lived in Bryan with his wife and ten-year-old son Donald. He was employed by the Agricultural Stabilization and Conservation Committee of the United States Department of Agriculture, working out of College Station. His boss described him as a "highly respected and dedicated public servant" who had been offered higher positions in Washington which he had refused, preferring to live in Bryan. Marshall carried a heavy work load which had caused him to have a "health problem" and threatened to reduce his working capacity to half-time. Some persons close to him were aware that Marshall had a bed in or near his office where he rested every day, and he told his brother-in-law, L. M. Owens, that he had a knot in his back which might be cancer. Others believed he had a heart condition, but whatever health problem he had it was not of recent origin. Marshall had lived with it a long time.
Saturday, June 3, 1961 was a day off, which offered Marshall the opportunity to go out to his ranch in Robertson County to look around and do some work. This "place"; as ranch or farm properties are sometimes called, was Marshall's hobby, his special interest, and he spent a lot of time at it. L. M. Owens worked for him on the place sometimes mending fences, seeing to crops and feeding the cattle. Owens noticed that Marshall recently had taken to driving in a back pasture where he looked over the feeder and talked quite a bit about it. It seemed a little unusual but Owens did not dwell on it. On June 3, Marshall stopped by the Owens house early before going thirteen miles northwest of Franklin to talk with Joe Pruitt and Wylie Grace, who with Lewis Taylor, were loading some hay on a truck. They were about ready to drive out of the Pruitt field when Marshall drove up in his Chevrolet pickup.
Marshall gave Pruitt a $36 check for baling hay and he tried to pay Grace for cutting the hay, but Grace declined. They visited for about twenty minutes and then, by 8:00 am, Marshall was gone. He went to his ranch and was involved in his normal activities and last seen at 10:30 a.m. by Jim and Martha Wood, a black couple who lived nearby. When he did not report home late in the afternoon, Mrs. Marshall called to get Owens to find him. Owens and Irving Bennett found him dead near the feeder at 6:30 pm.
When Robertson County Sheriff Howard Stegall, Deputy E. P. (Sonny) Elliott, and Ranger O. L. Luther arrived later, they looked around and decided it was suicide. Marshall had been shot five times with his .22 caliber rifle, which was found near the body. Marshall's glasses, watch, and pencils had been removed from their places and were on the seat of the pickup along with a single edge razor blade. At a quick glance it looked like suicide, and that is what they called it. No one paid attention to the fact that the rifle had a bolt action, one which had to be worked every time the rifle was fired. The following morning, Sunday, with the greenery of Central Texas at its best in late Spring (really early Summer in this locale) and the birds flitting and twittering overhead. Deputy Elliott took justice of the Peace Lee Farmer out to the scene. It looked like suicide to Farmer, so he recorded it as such in his official report. While there, Elliott picked up a spent .22 caliber cartridge casing.
Meanwhile the family gathered. From Denison about dawn on June 4 came Mrs. Marshall's sister and her two sons, nineteen-year-old Jackie Leroy Anderson and fifteen year-old Jerry Wayne Anderson. They were naturally curious as they looked at Uncle Henry's pickup which had blood smeared on it in several places, on the right side near the door handle, on the hood and right rear fender and on the left door just below the door handle. They also saw a dent, six to eight inches in diameter, centered in the lower half of the right door. Owens and the Anderson boys drove out to Marshall's farm that morning and just out of curiosity, placed the pickup at the same place Owens had found it. They then looked around and found a raisin box and some cigarette butts which had been smoked down to the filter so they could not tell what kind they were. They picked up the filters and put them in the raisin box which got lost later. Owens convinced them that it was suicide, saying, "Remember, I know more about Henry Marshall than you think I do. I worked for him and was with him a lot." When they got back to Franklin, Owens asked the young men to wash the truck, and they did.
Henry Marshall was buried as the family returned to normalcy. Mrs. Marshall soon went to Lee Farmer to ask that the cause of death be changed from suicide, but Farmer thought he was right, so he stuck to it. That ended things. Ended them that is, until May, 1962, when Secretary of Agriculture Orville Freeman stated that Henry Marshall had been a "key figure" in the investigation of the affairs of Billie Sol Estes. The connection was cotton allotments. Estes found cotton farming to be profitable so he set out in 1960 to grow all he could. He discovered that the only obstacle to growing more cotton and making more money was that the federal government imposed strict acreage controls in exchange for its price supports on cotton. The acreage allotment remains with the land and it cannot otherwise be sold or exchanged. Once acreage allotment for cotton is set, it stays with the land and is sold with it. The only exception to the rule is on land taken away by the right of eminent domain. When this happened, then the allotment could be transferred to other land bought by the same person within three years. These transfers had to be approved by the Department of Agriculture, and in Texas they were screened at College Station by Henry Marshall. Estes saw the loophole in cotton allotments and went right to it. He persuaded farmers in Texas, Oklahoma, Georgia and Alabama who had lost cotton land by eminent domain to purchase land from him. The plan was for a farmer to buy the land, place the cotton allotment on it, and then lease it to Estes for $50 per acre. The farmer was to pay Estes for the land purchase in four installments, but it was understood in advance that the farmer would fail to make the first payment, after which Estes would foreclose. The final result was that Estes still had the land, only now it was an acreage upon which cotton could be grown. By June, 1961, Estes was already in trouble over his cotton allotments because agriculture officials were onto his scheme, and it is a coincidence that he started getting in trouble at the same time as Henry Marshall's death. Homer Garrison had the "coincidence" called to his attention, after which he decided that a closer look should be had. Garrison assigned Peoples to investigate. Taking Ranger Johnny Krumnow with him, Peoples began on May 10, 1962, and he made his report to Garrison on July 13. In between, Rangers Krumnow, Hendrichs, Luther, Horton, Wilson, Riddles, J. S. Nance and Glenn Elliott had questioned everybody connected or possibly connected with the death. Mrs. Marshall, L. M. Owens, Irving Bennett, and Bob Marshall, Henry Marshall's brother, had all taken polygraph tests which showed that they knew nothing of how Marshall had met his death.
By May 21 Peoples had enough evidence to convince District Judge John M. Barron and County Attorney Bryan Russ to call a grand jury "for the purpose of obtaining evidence regarding Marshall's death." Peoples was the first to present for all the proceedings so he could hear witnesses' testimony. Fifty-five witnesses testified in the five weeks of hearings. The grand jury was concerning itself with whether it was suicide or homicide, but Peoples was already convinced it was the latter and he was trying to decide who had done it. That afternoon, judge Barron ordered that the body be disinterred for autopsy. Peoples was there when they brought the casket out of the ground to be taken to the Callaway-Jones Funeral Home in Bryan.
Dr. Joseph A. Jachimczyk, the chief medical examiner for Harris County, was called to Bryan to do the autopsy. Jachimczyk was a veteran in his trade, a man who had worked with some 15,000 corpses, one who performed autopsies daily. He was assisted by Dr. Ray Cruse of Hearne and James L. Turner, an investigator from his own staff. In addition to Peoples, those present were Judge Barron, Sheriff Stegall, Fred R. Rymer, DPS ballistics expert Charles H. Beardsley, Cal Killingsworth, and Dr. James I. Lindsay. The vault was opened at 7:30 a.m., the body identified by Manley Jones, the embalmer of almost a year ago, and the examination of the body began at 8:30. Jachimczyk was thorough in his work. He went through the body systematically looking at everything, describing the "thin layer of black mold, which scraped off fairly easily" and the "scalp which slipped readily off the calvarium upon touching." But such thing were incidental to the doctor's research. He wanted to know the cause of death. To this end he took ninety-seven specimens for examination.
His twelve-page report concluded that Marshall came to his death as a result of five gunshot wounds in the chest and abdomen. Three of the wounds were "rapidly incapacitating," while two would require a little more time. Marshall, he felt, could not have lived more that thirty minutes after he sustained the wounds. He found two further complicating factors. Marshall had a bruise on the left side of the head and he had a 15 per cent carbon monoxide saturation in the blood from the left chest cavity, which he said could have been as high as 30 per cent at the time of death. For the grand jury, the punch-line of the report was Jachimczyk's final conclusion: "Being familiar with bizarre gunshot injuries, one cannot say, however, on a purely scientific basis that a verdict of suicide is absolutely impossible in this case; most improbable, but not impossible." He pronounced it as a "possible suicide, probable homicide."
Dr. Jachimczyk telephoned his findings to Judge Barron on May 24 as the investigation proceeded. Peoples was in Austin the following day giving Garrison a briefing after which "The Boss" said to keep going. On May 29 and May 30 Peoples conferred with judge Barron, County Attorney Russ and the grand jury, and he did it again on June 4. June 3, the first anniversary of Marshall's death, found him in the maelstrom of a mystery. After the grand jury had considered the evidence presented, they concluded on June 25 that there was no reason to change the verdict from suicide. Jury Foreman Goree Matthews did state that they agreed to come back into session at any time to hear additional evidence. County Attorney Bryan Russ agreed, stating that he had "no evidence to indicate that it was other than suicide." Sheriff Stegall was asked if he thought Marshall could have worked the bolt on the rifle to reload after each shot, and he replied that he thought it possible. "I do know this," he continued, "a man can stand up under a lot of lead. A .22 does not have much shocking power... I saw a man hit four times once and walk off." Since that time the legal question of Marshall' death - suicide or murder - has not been opened.
For Peoples the case never stopped. He continued to have his Rangers follow every lead, doing the coordinating and analyzing himself. On July 13, 1962 he made an extensive report to Colonel Garrison, a part of which reads: Our investigation reveals that for Mr. Henry Marshall to have committed suicide the following acts would have had to occur:
 The first act of Mr. Marshall would have been to take carbon monoxide. (Pathologist's report reveals that 15% carbon monoxide was present at time of autopsy one year later and 15% would have been lost from embalming processes, a lethal dose consisting of 40%)
 Mr. Marshall would have had to dispose of the facilities with which the carbon monoxide was administered
 Mr. Marshall received a serious brain injury on the left side of his head from a fall and a cut over his left eye, causing the eye to protrude.
 Severe bruises with skin breakage on the back of his hands.
 Blood left on the right side of the pickup truck, also on rear and left side of pickup.
 Mr. Marshall would have had to cut off the motor on the pickup.
 Absence of blood inside of pickup after motor was cut off.
 Absence of blood on front of Mr. Marshall's shirt.
 Shirt of deceased was open with no bullet holes in front.
 Nitrites present only on tail of Mr. Marshall's shirt (back side).
 A deep dent present on right side of pickup caused by some type of instrument other than a human hand or head which was placed there on this date.
 Due to lack of blood on front of shirt but considerable blood present around pickup creates another mystery.
 Investigation revealed that it was difficult for Mr. Marshall to straighten out his right arm, which was due to a prior injury, and it would have been necessary for him to pull the trigger with his left hand.
After all of the above acts Mr. Henry Marshall would have had to have sufficient control of his equilibrium to have fired five bullets into the front of his left abdomen with a .22 bolt-action rifle, taking it down each time and ejecting the shell. The five bullets passing through Mr. Marshall's body traveled at a substantially straight angle which would indicate that he had to have extreme control of his equilibrium, after receiving all injuries from falls preceding the shooting of himself. From the direction of travel of bullets Mr. Marshall would have had entrance wounds which would have been more difficult. This fact was determined by the pattern of spent shells which were found by this Division and other parties after the death of Henry Marshall. Markers were placed by parties who found the spent shells at the time. Tests were made of the gun to establish a pattern of shell ejections which revealed that they were of a pattern identical to those found at the scene. Sand in the entire area was sifted; no bullets present. Mine detector was used; no other spent shells found.
A conclusion reached from this investigation is that had Mr. Henry Marshall shot himself before all of the acts above pointed out he would have had to return to where the empty shells were found and then collapse, which under the circumstances above mentioned would have been impossible for the following reasons: (1) Investigation reveals that there was no blood present on the ground other than where the body was found, (2) the only blood present on Henry Marshall's shirt was at the exit holes in the back and was a very small amount, (3) autopsy reveals that three of the shots were incapacitating, one severing the aorta and two paralyzing, and (4) autopsy report also reveals that the man died quickly from internal hemorrhaging.
It is a conclusion of this writer that Mr. Marshall did not live long after shots were fired into his body for the reason that so long as there is life in the body, the heart is pumping and so long as the heart is pumping, blood will flow from the exit of a gunshot wound. Reasonable deductions are that Mr. Marshall did not move from the location where the shots were fired into his body. It would have been impossible for him to have first fired the shots with such accuracy under the influence of carbon monoxide, secondly committed the acts above mentioned and return to the spot where the shells were found and died. It is reasonable to conclude that this would not have been possible for him to have returned and scuffed up the ground with his foot as indicated in a dying condition. Witnesses reveal that the ground was scuffed up with his foot where he was found lying.
An extensive investigation was conducted, as result of the suicidal ruling, to determine the reason for suicide motivation; no reason can be established. All reports reveal that Mr. Henry Marshall was a dedicated, honest and loyal government employee. Records also reveal that due to the vast operation of the cotton and grain program of Texas and Mr. Marshall's reluctance to approve many shady aspects he, without a doubt, created animosity among people who were attempting to accomplish their goals. From the findings of this investigation it is my personal opinion that it would have been beneficial to a vast number of shady operators for Mr. Henry Marshall to have been disposed of. It is my conclusion from the extensive investigation made by this department with the assistance of the scientific approach, evidence obtained, witnesses' testimonies, physical checks and tests made at the scene, it would have been utterly impossible for Mr. Marshall to have taken his own life.
A Texas Ranger, Clint Peoples, had befriended Estes and convinced him that he should come clean with the whole truth. True to his word, Estes agreed to appear before a Robertson County grand jury and clear the record concerning the cotton allotments, the death of Henry Marshall and the involvement of LBJ and others. He recounted the whole ugly picture - from the millions he had funnelled into Johnson's secret slush fund, to the illegal cotton allotment scheme, to the murder of Henry Marshall.
Estes testified that Lyndon Johnson, Cliff Carter (an aide of LBJ), Malcolm Wallace and himself met several times to discuss the issue of the "loose cannon" - Henry Marshall. Marshall had refused a LBJ-arranged promotion to Washington headquarters, and it was feared that he was about to talk. Johnson, according to Estes, finally said, "Get rid of him," and Malcolm "Mac" Wallace was given the assignment. According to testimony, Wallace followed Marshall to a remote area of his farm and beat him nearly unconscious. Then while trying to asphyxiate him with exhaust from Marshall's pickup truck, Wallace thought he heard someone approaching the scene, and hastily grabbed a rifle which customarily rested in the window rack of the truck. Quickly pumping five shots into Marshall's body, Wallace fled the scene.
On June 19, 1992, US Marshall Clint Peoples told a friend of his that he had documentary evidence that Mac Wallace was one of the shooters in Dealey Plaza. On June 23rd, Peoples, a former Texas Ranger and a onetime friend of Henry Marshall, was killed in a mysterious one-car automobile accident in Texas.
On March 12, 1998, a 1951 fingerprint of Malcolm "Mac" Wallace was positively matched with a copy of a fingerprint labeled "Unknown," a fresh print lifted on November 22, 1963, from a carton by the southeast sixth floor window of the Texas School Book Depository. This carton was labeled "Box A," and also contained several fingerprints identified as those of Lee Harvey Oswald. The identification was made by A. Nathan Darby, a Certified Latent Print Examiner with several decades experience. Mr. Darby is a member of the International Association of Identifiers, and was chosen to help design the Eastman Kodak Miracode System of transmitting fingerprints between law enforcement agencies. Mr. Darby signed a sworn, notarized affidavit stating that he was able to affirm a 14-point match between the "Unknown" fingerprint and the "blind" print card submitted to him, which was the 1951 print of Mac Wallace's. US law requires a 12-point match for legal identification; Darby's match is more conclusive than the legal minimum. As cardboard does not retain fingerprints for long, it is certain that Malcolm E. Wallace left his fingerprint on "Box A" on the sixth floor of the Texas School Book Depository early on November 22, 1963.
Publicity was given to one of the first whistle blowers to be killed, federal inspector Henry Marshall, an employee of the Agricultural Stabilization and Conservation Service. He was killed in June 1961 on a farm in Texas, much to the relief of high federal officials. Marshall had evidence linking a multimillion-dollar commodity fraud to an LBJ aide, and to Lyndon Johnson himself. Alongside Marshall's body was the .22 caliber rifle that had fired the fatal bullets. Texas authorities obligingly ruled Marshall's death a suicide, even though the position of the wounds indicated it would have been physically impossible for them to have been self-inflicted.
An AP article prepared by the Dallas Times Herald reported that convicted swindler Billy Sol Estes secretly testified before a grand jury empanelled at Franklin, Texas, relating to the Marshall death. Estes testified that he was present when Lyndon Johnson and two other men discussed having Marshall killed because Marshall knew too much about illegal manipulation of cotton allotments. Johnson reportedly gave the order to have Marshall slain. Estes identified the two men as Clifton Carter and Malcolm Wallace. Carter was once Johnson's top political aide in Texas and later his White House liaison to the Democratic National Committee. Wallace was a former University of Texas student body president.
The Marshall killing and its relationship to Lyndon Johnson had been the subject of intense gossip and rumor in Texas political circles for years. Estes, who had aged considerably since Marshall was killed, agreed to testify about the Marshall killing at the urging of U.S. Marshal Clint Peoples of Dallas, who had pursued the case for more than two decades.
Other testimony in the grand jury hearings revealed that Johnson approved the killing out of fear that Marshall would give Attorney General Robert F. Kennedy evidence concerning cotton allotments incriminating LBJ. Kennedy was known to have no respect for Johnson.
