WASHINGTON - King of pop Michael Jackson might have accidentally killed himself with deadly anaesthetic demerol, it has emerged.

According to Entertainment Tonight, the ‘Thriller’ hitmaker apparently woke alone in his bedroom and couldn’t find his personal physician Dr. Conrad Murray.

In a bid to get back to sleep, the troubled singer might have injected himself with a deadly shot of Demerol.

“Michael may have awakened from his induced sleep sometime in the middle of the night - and with no one around to help him - injected himself with a deadly shot of Demerol,” Contactmusic quoted a source as telling the show.

However, the show’s investigative reporter Diane Dimond said, “Once the toxicology report is released we’ll finally have answers.” (ANI)
