Sam Bernett, a former journalist with The New York Times, said Morrison was killed by a heroin overdose and his death was covered up by drug dealers, the Mail on Sunday reported.
Morrison, the lead singer of The Doors, officially died of "natural causes," but in an exclusive interview with the British newspaper Bernett revealed what he claims to be the truth.
Bernett alleges in his book, "The End -- Jim Morrison," that Morrison passed away because of a massive heroin overdose in the toilet of the Rock 'n' Roll Circus nightclub, which he was managing at the time.
The rock star's death reportedly was covered up by two drug dealers who transferred his body from the club to the singer's apartment.
French authorities are taking the allegations seriously enough to consider reopening the investigation into Morrison's death.
