Michael Jackson's Doctor Conrad Murray Trial Day 3: Doctor Tried To Hide the Vials

Michael Jackson's doctor Conrad Murray trial on Thursday, Sept. 29, focused on former members of Jackson's staff, including bodyguard Alberto Alvarez and chef Kai Chase, who testified that Murray tried to hide the vials of a strong medicine and a saline bag just before the paramedics arrived.

Bodyguard Alberto Alvarez took the stand, testifying that he saw Murray performing chest compressions on Jackson with one hand and used the other hand to put the drug vials in a bag, when he arrived at the scene. When Murray saw Alvarez enter the room, he asked Alvarez to remove the vials and the saline bag, which held a glass bottle of propofol.

While I was standing at the foot of the bed he (Murray) reached over and grabbed a handful of vials and then he said 'here put them in a bag', Alvarez said.

The bag had what appeared to me like a milky white substance. I recall seeing it at the bottom of the (saline) bag, Alvarez described.

It was only after the vials and the saline bag were placed in bags that Alvarez called for an ambulance to attend to Jackson.

When he asked why he listened to Muarry's order to hide the evidence, I believe that Dr. Murray had the best intentions for Mr. Jackson, so I didn't question his authority at the time. I thought we were packing to get him ready to go to the hospital, Alvarez said.

Prosecutors believed that the milky white substance was the surgical anesthetic propofol, which was the principal cause of Jackson's death on June 25, 2009, according to the authorities.

He was laying on his back, with his hands extended out ... his eyes were slightly open and his mouth was open, Alvarez said.

Kai Chase, Jackson's previous personal chef, also testified in the court. At the noon of day Jackson died, Chase was preparing his lunch for Jackson and his children. However, Murray burst into the kitchen and called them to get help, get Prince and get security. Chase said she did as she was told.

As the children came to Jackson's house, Prince and Paris came behind me. Paris screamed out 'Daddy!' Alvarez said.

Alvarez also noticed an IV stand, oxygen tubing around Jackson's nose and a condom attached to his penis, which collects urine while a person is sleeping. No heart monitor, blood pressure monitor or other monitoring equipment was in the room, he said.

Murray admits giving Jackson propofol as a sleep aid but denies involuntary manslaughter. Murray's defense attorney believe that Jackson gave himself an overdose of the drug, which can kill six people, when the doctor was out of room.

Murray could face up to four years in prison and lose his medical license, if convicted.
