Original 35mm black and white negative taken by Dallas Times Herald staff photographer William Allen. This image shows Dallas citizen Larry Florer in custody at the Dallas County Sheriff's Department on November 22, 1963. Florer had seen the presidential motorcade downtown and then heard on a radio that the president had been shot. He testified that he entered the Texas School Book Depository building approximately 15 minutes after the shooting, looking for a telephone. Dallas police took him to the County jail for questioning when a Depository employee pointed Florer out as a stranger who had been inside the building, which had been rapidly identified as the primary scene of investigation.Because the Dallas County sheriff's offices and jail were located along the eastern edge of Dealey Plaza, assassination eyewitnesses and people of interest were taken there for questioning. Dallas Police ordinarily took witnesses and suspects to their offices on the east side of town, at the intersection of Main and Harwood streets.
