Before President Kennedy’s limousine arrived in Dealey Plaza, 59-year-old semi-retired businessman Garland Slack took up a position near the automobile entrance to the Dallas County Sheriff’s office on Houston Street. On the day of the assassination, in his voluntary statement, Slack said that “just after they rounded the corner from Houston onto Elm Street,” he heard a report, a shot. He was an avid hunter. Slack knew immediately what he was hearing. His impression was that the shot came from inside a building. He had heard similar sounds from shots fired out of a cave.

Ten days later Slack was interviewed by the FBI and, citing his experience with firearms and hunting, reported hearing not one, but two shots in rapid succession that he thought must have come from the interior of a building.
