Legal Experts Discuss Propofol Evidence

Los Angeles - Michael Jackson's "logistics" director, who testified earlier this year that the singer's doctor collected medical vials and ordered him to remove a bag from an IV stand next to Jackson's body before telling him to call 911, was expected to take the stand today in the physician's involuntary manslaughter trial.

Alberto Alvarez was the first person to go into Jackson's bedroom after Dr. Conrad Murray found the singer unresponsive in his bed on June 25, 2009.

The singer was pronounced dead later that day at Ronald Reagan UCLA Medical Center.

Murray, 58, faces up to four years in state prison if convicted of the felony charge stemming from Jackson's death at age 50.

The cardiologist was working for the singer in his rented mansion, where Jackson was staying while rehearsing for a series of 50 sold-out concerts in London dubbed "This Is It." The singer died of acute propofol intoxication.

Prosecutors claim Murray gave Jackson the powerful sedative and then failed to monitor him, leaving the singer's bedroom for 45 minutes to make phone calls and send emails.

Defense attorneys insist Murray was weaning Jackson off the medication, but the singer "self-administered" a larger dose of the drug that killed him instantly after the doctor left the room.

Prosecutors also allege that prior to calling 911 or asking anyone else to do so, Murray collected vials of propofol and other equipment from Jackson's bedroom.

Also expected to testify today were Jackson's personal chef, Kai Chase, along with two paramedics, Richard Senneff and Martin Blount, who responded to the Holmby Hills home after 911 was called. The two testified at a preliminary hearing in January that by the time they arrived, it looked as if Jackson had not been breathing for at least 20 minutes, and he was already dead.

On Wednesday, the head of Jackson's security detail said the singer's young daughter was crying on the floor outside the singer's bedroom the day he died while Murray was administering CPR.

Faheem Muhammad said he was in the bedroom when he realized that Jackson's son, Prince, then 12, and daughter Paris, then 11, were just outside the singer's bedroom.

"Paris was on the ground, balled up, crying," he said, adding that Prince had a "shocked" look and appeared to be slowly crying.

Muhammad said he went to the children, talked to them and walked them downstairs, calling for help from a nanny, to make sure they were in a more secure location so they would not see what was happening. He later helped put Jackson's three children in a vehicle so they would not see their father's body being loaded into an ambulance.

Once they arrived at Ronald Reagan UCLA Medical Center, photographers were trying to swarm the paramedics and ambulance, and members of the security team used their jackets to shield Jackson's body and the kids, he said.

"There was a lot going on, with his family arriving and people trying to sneak in," Muhammad said, adding that the children were taken to a separate room at the hospital.

Also Wednesday, Jackson's personal assistant testified that after the singer had been pronounced dead at the hospital, Murray asked to be driven back to the Holmby Hills estate to get some "cream" from Jackson's bedroom.

"He said that there's some cream in Michael's room ... that he (Jackson) wouldn't want the world to know about," Michael Amir Williams testified.

Williams said he declined to take Murray back to the house and lied to him that police had taken his keys. He testified that he then instructed Muhammad to "make sure security doesn't let anyone in or anyone out" of the home.

Murray later approached him with a request for a ride to get some food, Williams said, noting that he shrugged off the request.

Williams testified that he first learned there was a problem with Jackson when he listened to a voice mail at 12:13 p.m. the day of the singer's death. In the message, Murray asked him to call back right away.

Jackson's personal assistant testified that he returned the doctor's call two minutes later, and Murray told him that "Mr. Jackson had a bad reaction" and to "get somebody up here right away."

"Were you asked to call 911?" Walgren asked.

"No, sir," Williams responded.

He said he didn't consider it to be an emergency situation at the time.

"When I hear someone had a bad reaction, I don't think anything fatal," Williams told jurors.
