The third day of testimony in the manslaughter trial against former Michael Jackson doctor Conrad Murray once again featured former members of Jackson's staff, bodyguard Alberto Alvarez and chef Kai Chase.

Alvarez took the stand first Thursday (September 29) to describe his arrival on the scene. He claimed when he entered the room, he saw Murray performing chest compressions on Jackson with one hand, and that when Murray heard Alvarez enter, he made the frantic request for Alvarez to remove several vials of [article id="1619831"]propofol[/article] -- the potent anesthetic that was part of the official cause of Jackson's death -- from the room before he called for an ambulance.

Jackson's former personal chef was next to testify. After going through a list of the food items she prepared regularly for MJ and his children, mostly healthy meals like granola with almond milk and juice blends, Chase revealed that on the day of Jackson's death, she was in the middle of preparing his lunch when a worried and panic-stricken Murray burst into the kitchen and shouted for her to "get help, get [son] Prince and get security." Chase said she "did as she was told" and went into the den to alert Prince and that she did her best to keep the children calm.

Testimony is set to resume again Friday at 8:45 a.m. PT. Murray has been charged with involuntary manslaughter and administering the dose of propofol that caused Jackson's death and faces four years in prison and the loss of his medical license if found guilty.
