I think I got out on the street about 12:15 or 12:20 - something along there. And we were looking around, back and forth. People were talking and laughing, and in a very good mood. And I looked at this building (Texas Book Depository) and saw a man with a gun, and there was another man standing to his right. I could not see all of this man, and I couldn't see his face.

The other man was holding a short gun. It wasn't as long as a rifle. He was holding it pointed down, and he was kneeling in the window, or sitting. His arms were on the window. He was holding the gun in a downward position, and he was looking downward. ...

Just as I was looking at this man the people started shouting "Here he comes, here he comes." So I looked the other way and forgot about the man.

The President passed us, and he was smiling, and everybody was waving. Then the last of the cars went by, and I heard the shot. I thought it was a firecracker. Then I started back to work, and it was along the curb, and then two shots right together, and then another one. I'm sure there were four shots.

And then I said "It's gunshots." And people started screaming. I told them that I saw the man had light hair, or brown, and was wearing a white shirt. I explained to the FBI agents that I wasn't sure about that. That was my impression on thinking about it later. That I thought that was the way the man was dressed. This other man was wearing a brown suit. That was all I could see, half of this man's body from his shoulders to his hips. He was facing the window. Evidently he was looking out. But his face was in the upper part, where the glass was dirty, and I couldn't see his face....

The first statement that I made, I said the man was on the fourth or fifth floor, and I still feel the same way.

Assassination of John F. Kennedy Encyclopedia

There were also witnesses who told independent investigators of threats and harassment which allegedly occurred long after their testimony. These were usually witnesses who were quite vocal and public about what they had seen in Dallas. For example, Richard Randolph Carr told independent investigators of pressure and harassment from the FBI and police as well as threatening phone calls and indicated that these had played a role in his decision to move from Dallas to Montana. On the day of the assassination Mr. Carr swore that he observed a man near the alleged assassin's window who was not Lee Harvey Oswald. His description dovetailed perfectly with the description of one of the two armed men observed minutes later in the alleged assassin's window by Mrs. Carolyn Walther who also signed an affidavit following the assassination. After the shots Carr noticed a man walking away from the Book Depository Building who he thought was the same man he had seen in the window and actually followed him for several blocks' The man got into a light colored Rambler station wagon with a luggage rack on the roof with Texas license plates and was driven away by a swarthy skinned man. Minutes later a similar man and car were observed by two witnesses as they made a Buick pickup of a man running from the general area of the Book Depository Building. A deputy sheriff, Roger Craig, identified the man who was picked up as either Lee Harvey Oswald or someone who looked a lot like him. (The Commission places Oswald in another part of town at that moment.) Craig, who allegedly complained to Warren Report critics of threats and attempts on his life, committed suicide in May of this year.
