On October 4th, 1970, Janis Joplin was found dead in her home by a friend.

Joplin's autopsy report said investigators found paraphernalia like gauze with dried blood in the garbage, a "hype kit" — a set-up for shooting up drugs that included a syringe and needle — and a teaspoon with the tell-tale black smudge on the bottom where a lighter is held to cook drugs before pulling them into the syringe and injecting them. They also found powdered drugs, pills, and suspected marijuana.

The autopsy report would confirm that Joplin died of acute heroin-morphine intoxication due to an "injection of overdose." The medical examiner noted there were "numerous" needle marks on her arms, described as "old needle marks and some are of relatively recent origin."
