British singer Marianne Faithfull claims her drug-dealing ex-boyfriend “killed” Jim Morrison after accidentally supplying him with heroin that was too strong.

Faithfull, the former girlfriend of Mick Jagger, told music magazine MOJO she is now the only person alive “connected” to Morrison’s death, claiming she was in Paris with her drug-dealing boyfriend the summer The Doors frontman died.

Faithfull, who co-wrote the Rolling Stones song Sister Morphine told the magazine the late drug dealer, Jean de Breiteuil, was to blame for Morrison’s untimely death on July 3, 1971, at the age of 27.

Faithfull, who also struggled with drug issues, said she traveled to Paris in the summer of 1971 with de Breiteuil.

Upon their arrival in Paris, Faithfull claims de Breiteuil told her he was paying a visit to Morrison’s apartment. Having a bad feeling about the visit, Faithfull said she chose to stay in her own hotel room taking downers rather than accompany de Breiteuil to the apartment.

“I could intuitively feel trouble,” she recalls. “I thought, I’ll take a few Tuinal and I won’t be there. And he went to see Jim Morrison and killed him. I mean I’m sure it was an accident. Poor bastard. The smack was too strong? Yeah. And he died. And I didn’t know anything about this. Anyway, everybody connected to the death of this poor guy is dead now. Except me.”

Although no autopsy was ever performed, Morrison is believed to have died from a heroin overdose.

Official reports said he had a heart attack in the bath. The coroner did not suspect foul play so did not order an autopsy.

The mystery surrounding Morrison’s death lingers amid conflicting tales of the singer’s last days and a slew of conspiracy theories.

Morrison’s girlfriend at the time, Pamela Courson, said he woke coughing in the night before heading into the bathroom to soak in the tub. Another friend claimed he died in the bathroom of a nightclub after an overdose and his body was moved to his apartment in a cover-up.

De Breiteuil also died of an overdose in 1971, not long after Morrison’s death.
