Defense witness: Michael Jackson caused own death

LOS ANGELES -- Attorneys for Michael Jackson's doctor dropped the bombshell Friday they've been hinting at for months -- an expert opinion accusing the legendary singer of causing his own death.

Dr. Paul White, the defense team's star scientific witness, said Jackson injected himself with a dose of propofol after an initial dose by Dr. Conrad Murray wore off. He also calculated that Jackson gave himself another sedative, lorazepam, by taking pills after an infusion of that drug and others by Murray failed to put him to sleep. That combination of drugs could have had "lethal consequences," the researcher said.

White showed jurors a series of charts and simulations he created in the past two days to support the defense theory. He also did a courtroom demonstration of how the milky white anesthetic propofol could have entered Jackson's veins in the small dose that Murray said he gave the insomniac star.

White said he accepted Murray's statement to police that he administered only 25 milligrams of propofol after a night-long struggle to get Jackson to sleep with infusions of other sedatives.

"How long would that (propofol) have had an effect on Mr. Jackson?" defense attorney J. Michael Flanagan asked.

"If you're talking effect on the central nervous system, 10 to 15 minutes max," White said.

He then said Jackson could have injected himself with another 25 milligrams during the time Murray has said he left the singer's room.

"So you think it was self-injected propofol between 11:30 and 12?" Flanagan asked. "In my opinion, yes," White said.

The witness, one of the early researchers of the anesthetic, contradicted testimony by Dr. Steven Shafer, his longtime colleague and collaborator. Shafer earlier testified Jackson would have been groggy from all the medications he was administered during the night and could not have given himself the drug in the two minutes Murray said he was gone.

"He can't give himself an injection if he's asleep," Shafer told jurors last week. He called the defense theory of self-administration "crazy."

White's testimony belied no animosity between the two experts, who have worked together for 30 years. Although White was called out by the judge one day for making derogatory comments to a TV reporter about the prosecution case, White was respectful and soft-spoken on the witness stand.
