At the Reynolds Motor Co. (southeast corner of Jefferson and Patton), four men heard the gun shots, looked north toward the sound of the shots and saw a man running south on Patton (towards their location) with a gun in his hands.
Harold Russel, L.J. Lewis, Pat Patterson and Warren Reynolds were these four men.
After seeing the man head west on Jefferson, Lewis went inside the office and called the police.
Russell went up Patton to the location of the shooting. Ted Callaway approached Russell with the idea of taking Tippit's service revolver and going after the killer. Russell told Callaway that he (Russell) was going to stay at the scene so that he could give the police information when they arrived. He was present there when then police arrived.
Warren Reynolds suggested to Pat Patterson they they follow the gunman. The two followed the man for a block until they lost sight of the man as he went north on Crawford beside the Texaco station located at the corner of Jefferson and Crawford. Reynolds and Patterson approached a lady at the station (Mary Brock) and asked her if they saw the young white man. Brock told them that she had seen a man walk past her and and go to the lot behind the station. Reynolds was present in the lot when the police arrived, assuring the officers on the scene that the man was still somewhere in the area. This is the same parking lot where the Oswald's jacket was found.
Russell, Patterson, Reynolds and Brock were each shown a photograph of Oswald and all were of the opinion that the man they saw was Oswald.
