According to the autopsy report released on Friday, the pilot of the helicopter that crashed while carrying Kobe Bryant and his daughter to a basketball tournament in California did not have alcohol or drugs in his system.

The pilot, Ara Zobayan, 50, was taking the Bryants and six others to a youth tournament when the chopper slammed into the mountains west of Los Angeles, killing all nine on board instantly.

"Toxicological testing did not detect the presence of alcohol or drugs of abuse," the Los Angeles County coroner's report said.

The clinical report described the carnage at the January 26 crash scene and said that all the victims died of blunt force trauma. The manner of death for each was listed as accidental.

The investigation showed the helicopter was traveling at 296 kilometers per hour (184 mph) when it crashed into the hillside after running into heavy fog and cloud cover. Police said the helicopter plunged several hundred feet before impact.
