Dallas Law Enforcement at Dealey Plaza

During the shooting, Dallas motorcycle patrolman Bobby Hargis stopped his motorcycle on Elm Street and ran up a nearby grassy knoll. Marrion Baker, another police "motor jockey," parked near the Texas School Book Depository and ran to the entrance. Other officers quickly joined in the search for suspects and evidence, which ultimately led away from the knoll and railroad yards and into the Depository building. Within a few minutes, the building was sealed as police and sheriff's department officials began a systematic floor-by-floor search.

Shortly after 1:00 p.m., building supervisors took roll calls of Depository employees. Police soon began searching for Lee Harvey Oswald, who was the only one unaccounted for. At about 1:12 p.m., three spent bullet cartridges were discovered by Deputy Sheriff Luke Mooney under an open window hidden by a barricade of boxes—now known as the sniper's nest—in the southeast corner of the sixth floor. Ten minutes later, in the northwest corner of the same floor, Deputy Sheriff Eugene Boone found a bolt-action Mannlicher-Carcano rifle hidden between boxes near the corner stairwell.
