Jim Morrison died in Paris at the age of 27 on July 3, 1971. He was found in a bathtub at his apartment at 17 Rue Beautraillis by his girlfriend, Pamela Courson. A doctor’s report stated the cause of death was heart failure aggravated by heavy drinking. However, over the years there have been various conflicting reports about how Morrison really died. In the book “The End: Jim Morrison” written by Sam Bernett the former manager of a Paris nightclub has claimed that Doors frontman Jim Morrison died in a toilet stall at the club from a heroin overdose. This challenges the testimony of girlfriend Pamela Courson that Morrison died from heart failure while taking a bath. In the book Bernett claims two drug dealers found Morrison’s body in the toilet stall of Paris’ Rock and Roll Circus club on July 3, 1971, and dragged him back to his apartment. In an attempt to revive him, they placed him in the bath. Bernett writes, “When we found him dead, he had a little foam on his nose, and some blood too, and the doctor said, ‘That must be an overdose of heroin.’”

Morrison was buried at P’re Lachaise cemetary in Paris, which houses the remains of many famous artists, including Edith Piaf and Oscar Wilde. In 1990 his graffiti-covered headstone was stolen. Since Morrison’s burial it’s become one of the most famous rock and roll gravesites.
