John Adam Belushi (January 24, 1949 – March 5, 1982)

On March 5, 1982, after showing up at his hotel for a scheduled workout, his trainer, Bill Wallace found Belushi dead in his room, Bungalow 3 at the Chateau Marmont on Sunset Boulevard in Hollywood, California.[14] He was 33 years old. The cause of death was an overdose of cocaine and heroin, a drug combination also known as a speedball. In the early morning hours on the day of his death, he was visited separately by friends Robin Williams and Robert De Niro, each of whom left the premises, leaving Belushi in the company of assorted others, including Catherine Evelyn Smith. His death was investigated by forensic pathologist Dr. Ryan Norris, among others, and, while the findings were disputed, it was officially ruled a drug-related accident.
Two months later, Smith admitted in an interview with the National Enquirer that she had been with Belushi the night of his death and had given him the fatal speedball shot. After the appearance of the article "I Killed Belushi" in the Enquirer edition of June 29, 1982, the case was reopened. Smith was extradited from Toronto, Ontario, arrested and charged with first-degree murder. A plea bargain reduced the charge to involuntary manslaughter, and she served fifteen months in prison.
