MICHAEL AMIR WILLIAMS, MJ'S ASSISTANT TESTIFIED 01\04

The prosecution began to paint a picture of Dr. Conrad Murray's reckless actions on the night MJ passed away ... by calling to the stand the Jackson assistant Murray telephoned before he called 911.

Michael Amir Williams testified that he received a frantic voicemail from Murray at 12:13 PM on June 25, 2009. Williams said Murray's VM said, "Where are you? Get here right away, hurry."

Williams says he then called Alberto Alvarez, MJ's security guard, and asked Alvarez to walk to the front door. Williams says he heard Murray's voice in the background, then Alvarez hung up.

Williams said that later on at the hospital, Murray approached him and said Michael had some cream in his room that Murray knew MJ wouldn't want the world to know about. Williams said he wanted someone to give him a ride back to MJ's house to retrieve it.

Murray's baby mama, Nicole Alvarez, was in court today -- but ordered to return on Friday. Murray was on the phone with Alvarez when he realized MJ was in trouble.
