LOS ANGELES (RNN) - A retired anesthesiologist was adamant Monday that he thought Michael Jackson "probably self-administered propofol."
In a sometimes strained and argumentative cross-examination, the prosecution asked Dr. Paul White about scenarios he believes may make sense of how Jackson could have overdosed on the surgical anesthetic.
The IV stand the pop star was hooked up to had wheels on it making it possible, in White's examination, for Jackson to have gotten up while Dr. Conrad Murray was out of the room and move about the room. He believes Jackson grabbed a syringe of propofol and injected it into the IV drip he was getting at the time of his death.
"I don't think he realized the potential danger," White said.
He acknowledged the possibility that Murray had lied during his police interview, where he told police he had given only a small amount of propofol to the performer. However, Jackson overdosing on his own fit the amounts of propofol and other drugs found during his autopsy, according to White.
He could not justify Murray's delay in calling emergency services when he found Jackson, but also said he didn't think it would have made a difference in the case.
On March 8, he submitted a letter to the prosecution giving two different scenarios to explain Jackson's overdose. One was that Jackson self-administered the drug; the other was that Jackson had orally ingested the anesthetic, an idea that was later found to be impossible.
White admitted that at the time of the letter, he had not researched propofol and its affects thoroughly.
"Since there was not any literature and it had not been studied, I thought it would be good to cover all the bases," White said.
The second scenario was refuted after defense attorney Michael Flanagan commissioned a study on the claim which subsequently found that swallowing propofol would not cause death.
White admitted that he would not have administered the drug in a home-setting, as it was not a standard use for propofol.
"I think he [Murray] provided a service that Michael Jackson insisted on," he said.
The defense has paid the anesthesiology specialist $11,000 so far for his time in the case. He told prosecutors that he would not be seeking more compensation, save for maybe the cost of flights from San Francisco to the trial in Los Angeles.
He is the last witness for the defense. The trial is expected to go to the jury later this week.
Murray, Jackson's former doctor, is being charged with involuntary manslaughter after the performer's overdose in 2009. If convicted, he could face up to four years in prison.
