The world may have lost the iconic King of Pop, but on a day in June, 2009, his children suddenly lost their father.
Michael Jackson's bodyguard Faheem Muhammad testified Wednesday in the Conrad Murray involuntary manslaughter trial
, saying that he entered the star's bedroom minutes after his death and saw Jackson's two oldest children watching in horror.
"Paris was on the ground, balled up and crying," Muhammad testified, adding that "Prince had a really shocked, just slowly crying kind of look."
He said that Jackson lay sprawled diagonally across his bed, his eyes open and his mouth slightly open, as Jackson's doctor Conrad Murray – who was in court for the second day of his trial
– frantically tried to revive him.
"He appeared to be administering CPR," Muhammad testified. "He appeared very nervous. He was sweaty."
During the testimony, Jackson’s family, including sister Janet, listened intently. Jackson's mother Katherine clutched a tissue and looked down.
Muhammad also testified he had the nanny take the children away so they wouldn't see the paramedics carry Jackson out. Then he called security at UCLA's hospital to warn that paparazzi were already in the trees outside the house and would likely try to sneak in to Jackson's hospital room.
Prosecutors say Murray was grossly negligent, administering the hospital-strength anesthetic propofol without using proper monitoring equipment or even making sure someone was always in the room.
