Los Angeles Police Department investigators have released autopsy reports for nine people who died in a helicopter crash on January 26 in Calabasas.
The report states that it was determined that Kobe Bryant, a global sports star, used the drug methylphenidate (Ritalin), which is on the list of prohibited substances of the World Anti-Doping Agency, because it increases the explosiveness and strength of competitors.
According to the report, the pilot Ara Zobajan did not use alcohol or any type of medication or drugs.
The report also states that all the passengers of the helicopter lost their lives in the fall of the aircraft, because the impact was devastating.
Kobe Bryant, his 13-year-old daughter Gianna and seven other people died after a helicopter crashed into a hill due to fog.
The causes of the tragedy are still being investigated.
