Witness: Jackson doctor bought 255 anesthetic vials

LOS ANGELES -- A pharmacist testified Monday that the doctor charged in Michael Jackson's death bought 255 vials of a powerful anesthetic in the three months before the singer died from a lethal combination of the drug and other sedatives.

Dr. Conrad Murray purchased four shipments of the anesthetic propofol between April 6 and June 10, 2009, said Tim Lopez, owner of Applied Pharmacy Services in Las Vegas, where Murray has a clinic.

Murray bought 130 vials of propofol in 100 milliliter doses and another 125 vials in the smaller dose of 20 milliliters, Lopez said while testifying at a preliminary hearing to determine if there is enough evidence for Murray to stand trial after pleading not guilty to involuntary manslaughter.

A coroner's investigator previously testified that 12 vials of propofol were found in the bedroom and closet of the singer's rented mansion after his death.

Lopez said Murray asked him to ship some of the propofol to an address in Santa Monica, Calif. The address belongs to the doctor's girlfriend, although Lopez testified that Murray told him it was one of his clinics.

Murray also bought other sedatives from Lopez, according to the testimony.

Murray has told police he was concerned Jackson was addicted to propofol, and that he was trying to wean the singer from it.

The hearing has included a significant amount of prosecution evidence. Among the witnesses was a bodyguard who said he was told by Murray to place vials of medicine in bags before calling 911.

Paramedics and an emergency-room doctor with a combined 50 years of experience also said they believed the singer died before he was rushed by a paparazzi-hounded ambulance to a nearby hospital, where efforts failed to revive the pop superstar.

Using phone records and testimony from police and Murray's current and former girlfriends, prosecutors have developed the timeline that shows Murray was on the phone throughout the morning of Jackson's death on June 25, 2009, including after administering propofol to the singer.

They hope to convince a judge of several key points: that Murray was distracted when he should have been monitoring Jackson, that he delayed calling 911, that he botched CPR efforts and that the singer was dead before help was summoned.

The remainder of the hearing was likely to take a clinical approach, with coroner's officials, propofol experts and police who interviewed Murray taking the stand.

Pastor said Friday that prosecutors told him they were ahead of schedule, although he did not indicate when the hearing may end. Prosecutors appeared to be at least halfway through presenting their case.

Defense attorneys rarely present witnesses or their own theories during preliminary hearings. In Murray's case, they did not make an opening statement and have only hinted at potential arguments as they questioned witnesses.

Murray could face up to four years in prison if tried and convicted.
