Jackson's chief security guard, Faheem Muhammed, testified that both children were present when their father was lying on his bedroom floor with his eyes and mouth wide open, completely unresponsive to those around him.
"Paris was on the ground balled-up crying and Prince, he was just standing there, he had a real shocked -- just slowly crying -- look on his face," Muhammed said.
Murray, meanwhile, allegedly asked Muhammed and another security guard, "Does anyone know CPR?" Prosecutors allege that Murray caused Jackson's death by giving him the anesthetic propofol, neglecting his health and failing to provide prompt medical assistance to the singer during the incident.
To bolster that claim, prosecutors provided a timeline of the events, saying that Murray discovered Jackson's lifeless body at 11:56AM PT. At 12:13, he called Jackson's assistant, Michael Williams, and left a terse voicemail: "Call me right away."
Williams responded at 12:15 and was told by the doctor that the singer had suffered a "bad reaction." An ambulance was finally called at 12:20. Williams also testified that Murray, after his patient was officially pronounced dead, asked to be driven back to Jackson's rented house to dispose of "some cream in Michael's room that he wouldn't want the world to know about." It was implied that Murray used this trip to dispose of evidence against him.
This surprising revelation follows the prosecutor's decision to display a photo of Jackson's corpse lying on a hospital bed. Murray is facing four years in prison if convicted.
