Conrad Murray trial: In-depth look at Michael Jackson death from UCLA doctors


Jackson's death was pronounced twice before his body was ultimately transported to the county coroner. Both Dr. Richelle Cooper and Dr. Thao Nguyen testified that all signs indicated that the King of Pop was dead before he arrived at the emergency room.

At Murray's insistence, they persisted trying to save him. But Cooper said she never felt a pulse on Jackson.

"Dr. Murray asked that we not give up easily and try to save Michael Jackson's life," Nguyen said. "In Dr. Murray's mind, if we called it quits, we would be giving up easily."

More than 14 members of the emergency room team worked for an hour and 13 minutes to try to revive Jackson.

Nguyen, a cardiac specialist, said she was puzzled that Murray, an attending physician, could not explain what happened.

"He said that Mr. Jackson had been very tired. He was preparing for a concert tour in England and had been asking for some medications to help him go to sleep," Nguyen said.

Murray also could not recall when he gave Jackson another sedative that morning, Nguyen testified.

"He said he did not have any concept of time, he did not have a watch," she said.

While both doctors testified that Murray failed to tell them that he had been giving Jackson propofol, Cooper admitted that knowing propofol was administered would likely not have made a difference because when Jackson became her patient, he had been clinically dead for some time.

The prosecution maintains that Jackson died of an overdose of propofol administered by Murray, while the defense contends that Jackson administered the drug to himself.

Late Monday, ABC News learned that Jackson's fingerprints were not found on any propofol bottles from that room.

"He reported that Mr. Jackson had been working very hard, that he was, he thought, dehydrated, and he reported he'd given him two milligrams of lorazepam, and then later in the morning, he'd given him two milligrams of lorazepam and observed the arrest," Cooper said. Lorazepam is a mild sedative.

Cooper said in her practice, she has never used the powerful sedative outside a hospital setting, and Nguyen agreed: "I've never heard of propofol being used outside of a hospital."

Cooper testified that she saw Jackson's children at the hospital, saying they were crying and "fairly hysterical." She said she allowed Murray to assume care for Jackson en route to the emergency room because Murray told her he felt a pulse.

"There was a physician on scene, and then I had potentially conflicting information," Cooper said.

The prosecution laid out a timeline for jurors, characterizing Murray as haphazard in tending to Jackson. Edward Dixon, an AT&T representative, and Jeff Strohm, a Sprint representative, were called to the stand to testify Monday.

Murray's cellphone records are a window into his activities as he was at Jackson's bedside. He was using two cellphones. Representatives from the phone companies testified that Murray made or received 11 phone calls, totalling almost 90 minutes, in the hours leading up to Jackson's death. The most significant was an 11-minute phone call, just before 11:51 a.m., to Sade Anding, a Texas cocktail waitress who prosecutors believe was talking with Murray realized Jackson wasn't breathing.

Prosecutors sought to show the court that hours before Jackson's death, Murray had other things on his mind, including getting his deal approved to serve as Jackson's personal doctor while on the "This Is It" tour.

Murray is on trial for involuntary manslaughter for Jackson's sudden death on June 25, 2009, at the age of 50. Prosecutors allege Murray tried to hide the fact that he had been giving propofol to Jackson.

Murray, 58, has pleaded not guilty and has denied any wrongdoing. If convicted, he could face up to four years in prison and lose his medical license.

The trial is expected to last five weeks, with Oct. 28 being the estimated last day.
