According to the British Sun newspaper, an aide administered an injection of the narcotic painkiller Demerol to pop singer Michael Jackson in the early morning hours of June 25 while Jacko’s doctor slept.

This adds plausibility to earlier reports that Jackson was given a shot of Demerol that preceded his cardiac arrest on June 25th. The Sun claims Jacko’s personal physician Dr. Conrad Murray administered the short-acting potent sedative Diprivan (Propofol) a drug that is used to induce anesthesia.

After starting Jackson’s infusion of Diprivan, Dr. Murray told the LAPD he went to sleep. This goes against medical protocol since a patient receiving Diprivan IV requires constant monitoring of his breathing and blood pressure in a hospital setting.

According to The Sun, the Diprivan ran out during the night, and because Diprivan is short-acting, Jackson awoke soon after. Supposedly, Jackson then pleaded with an aide to give him a shot of Demerol.

Jackson’s death was recently ruled a homicide. Earlier in the investigation, Jacko’s dermatologist, Dr. Arnold Klein, admitted prescribing Demerol for Jackson. Federal agents and local police raided Dr. Murray’s Las Vegas home and Houston office last week. The agents were armed with search warrants listing Diprivan and other items related to the homicide case.
