Janis Joplin died at the Landmark Motor Hotel (currently known as the Highland Gardens) on Sunday, October 4, 1970 of a heroin overdose.
Earlier the previous evening, Joplin had been at Barney's Beanery with some cohorts. Joplin was apparently bummed out that she had been stood up by her friends recently, and had been given a particularly potent batch of heroin.
When Joplin failed to show up at her recording session at Sunset Sound Records on October 4, her producer Paul Rothchild visited the Landmark Motor Hotel. He discovered Joplin's body in her room (#105). She was 27 years old.
