At 12:15 a.m. on June 5, 1968, Senator Robert F. Kennedy had just delivered his California presidential primary victory speech in the ballroom of the Ambassador Hotel in Los Angeles. Rather than exit through the ballroom, his security team guided him through the hotel’s kitchen pantry — a shortcut to the press room.

In the pantry, Sirhan Bishara Sirhan, a 24-year-old Palestinian immigrant, opened fire with a .22 caliber Iver Johnson Cadet revolver. Kennedy was hit three times. He fell to the concrete floor of the kitchen, conscious but gravely wounded. Five bystanders were also hit.

Robert Kennedy died at Good Samaritan Hospital at 1:44 a.m. on June 6, 1968. He was 42 years old.

The Coroner’s Autopsy

Dr. Thomas Noguchi performed the autopsy — one of the most significant of his career. His findings were precise and would later become central to the controversy:

  • Three gunshot wounds, all entering from the right rear
  • The fatal shot entered behind the right ear, traveling upward through the brain
  • Powder burns indicated the fatal shot was fired from a distance of approximately one inch
  • A second wound entered the right armpit from the rear
  • A third bullet passed through the right shoulder pad of Kennedy’s suit without entering his body

Noguchi’s autopsy was meticulous. He brought in a team of forensic consultants and documented every detail with photographs and diagrams. The medical evidence was never seriously disputed.

The Ballistic Problem

The controversy centered not on the autopsy but on the ballistics. Noguchi determined that the fatal shot was fired from behind Kennedy’s right ear at near-contact range — approximately one inch. But every eyewitness placed Sirhan in front of Kennedy, at a distance of several feet.

This discrepancy fueled decades of second-gunman theories:

  • The muzzle distance — Witnesses consistently described Sirhan firing from two to five feet in front of Kennedy. Noguchi’s powder-burn analysis showed the fatal shot came from approximately one inch behind the right ear.
  • The bullet count — Sirhan’s revolver held eight rounds. At least twelve bullet holes were identified in the pantry, leading investigators to argue that a second gun must have been fired.
  • The door frame bullets — LAPD photographs showed bullet holes in the pantry door frames that, if confirmed, would account for more rounds than Sirhan’s gun could hold. The LAPD later destroyed the door frames, claiming they were not evidence.

The LAPD Investigation

The LAPD’s handling of the case drew criticism for decades:

  • Audio recordings from the pantry suggested more than eight shots were fired
  • Key evidence was destroyed, including the door frames and ceiling tiles with bullet holes
  • Witness statements that contradicted the lone-gunman narrative were reportedly downplayed
  • Security guard Thane Eugene Cesar, who was standing directly behind Kennedy and drew his weapon, was never thoroughly investigated

Sirhan was convicted and sentenced to death, later commuted to life imprisonment. He has consistently claimed he has no memory of the shooting.

Noguchi’s Precision

The Kennedy autopsy became the gold standard for forensic pathology in assassination cases. Noguchi’s work was so thorough that it survived every challenge — even as the investigation around it crumbled.

The irony of the Kennedy case is that the coroner did everything right. The autopsy was beyond reproach. But the physical evidence it revealed — the angle, the distance, the powder burns — pointed to conclusions that the official investigation could not explain.

The case remains one of the most studied assassinations in American history, and Noguchi’s autopsy report continues to be the foundation on which every theory, official or otherwise, must rest.
