Michael Jackson died from a lethal dose of a powerful anaesthetic and his personal physician Dr Conrad Murray is the prime suspect.

The king of pop, Michael Jackson, was murdered with a lethal drug cocktail – and the personal physician with him when he died is the key suspect, according to reports from the US.

A law enforcement official today said the Los Angeles County coroner had ruled Jackson died from a killer dose of a powerful anaesthetic, as well as two sedatives.

The finding makes increasingly likely criminal charges will be filed against Jackson’s personal physician, Dr Conrad Murray, who was with him when he died.

The official told Associated Press the coroner had found a fatal combination of drugs was given to Jackson in his rented Los Angeles mansion hours before he died on June 25. The official spoke on condition of anonymity because the findings have not been publicly released.

Dr Murray is already the subject of a manslaughter probe headed by Los Angeles police.

The official told AP the coroner determined a fatal combination of drugs was given to Jackson hours before he died in his rented Los Angeles mansion.

The claim came as a report by the Los Angeles chief medical examiner unsealed in a Houston court today revealed Jackson’s body contained a lethal level of the powerful anaesthetic propofol, also know as diprivan.

Jackson suffered cardiac arrest and died on June 25 at age 50. Since then, a police investigation into his death appears to have focused on the use of prescription drugs and the role of doctors who treated him, including his personal doctor, Conrad Murray.

“The Los Angeles Chief Medical Examiner-Coroner, Dr Sathyavagiswaran, indicated that he had reviewed the preliminary toxicology results and his preliminary assessment of Jackson’s cause of death was due to lethal levels of propofol (diprivan),” according to a search warrant affidavit for Dr Murray issued by California.

The document was released by the Harris County District Clerk in Houston, where Dr Murray has offices, which US agents raided on July 22 in a search for evidence of manslaughter. — Agencies
