Source: Michael Jackson Was Self-Injecting Demerol

A doctor who treated the late Michael Jackson claimed that the singer self-injected Demerol into his system, according to the file from his 2005 molestation trial.

In the Santa Barbara County Sheriff's notes, a member of Jackson's security detail - a retired L.A. County Sheriff's deputy named Michael Laperruque - said at least several doctors were trying to get Michael Jackson off of Demerol at the time.

One of the doctors "was upset with Jackson because he had been self-injecting."

A Demerol overdose has been suggested as a possible cause of death for the music icon, who passed away suddenly on June 25 after suffering cardiac arrest.

Laperruque told detectives he had picked up Jackson's prescriptions for the star, usually under the name Chris Carter. Carter was one of Jackson's bodyguards.

Also, Laperruque said that one time when he was at Neverland Ranch, his job was to keep Jackson's family out because they were planning an intervention.

Meanwhile, sources say that a pair of doctors at the center of the inquiry into Jackson's death - Dr. Arnold Klein and Dr. Conrad Murray - have not turned over the medical records the L.A. County Coroner's office has requested.

According to TMZ, both doctors have turned over some records, but the coroner's office has not gotten complete Jackson medical records from either doctor.

And there's this:

A driver for Michael Jackson told the coroner's officials shortly after Jackson's death that the singer was going to see Dr. Arnold Klein multiple times a week in the months preceding his death and sometimes would spend 3-4 hours inside.
