Jackson doctor bought propofol in Vegas

LOS ANGELES, Nov. 20 (UPI) -- Investigators in Michael Jackson's homicide case say they have linked Dr. Conrad Murray to propofol bottles found at the pop star's Los Angeles home.

Murray, Jackson's personal physician, allegedly bought the anesthesia from a Las Vegas pharmacy a month before the singer's June 25 death and had it shipped to Los Angeles, the Los Angeles Times cited court records unsealed Friday as saying.

Investigators in the case say the lot numbers on bottles found in Jackson's rented mansion matched those on a receipt found in Murray's Las Vegas office.

The 50-year-old entertainer's death was ruled a homicide after lethal levels of propofol and sedatives were found in his system.

Murray told police he administered the anesthesia to Jackson shortly before his death to help him sleep. The doctor also said the recording artist was addicted to the drug and he had been trying to help Jackson kick the habit.

No criminal charges have been filed in connection with Jackson's death.
