Michael Jackson's oldest son described the frantic efforts to revive his father to a jury, a scene of tears and agony that ended a dozen idyllic years being raised by one of pop music's superstars.
Michael Joseph 'Prince' Jackson Jr told the panel how he knew there was trouble in the singer's rented mansion when heard screaming upstairs and went into his father's bedroom.
His father was laying halfway off the bed, eyes rolled up into the back of his head as his physician tried CPR.
His sister Paris screamed for her father and Prince, now 16, told jurors that he was crying.
On the ride to a hospital, the teenager recounted how he tried to calm the fears of his sister and younger brother by telling them that angels were watching over their father and everything would be fine.
It wasn't until his father's doctor, Conrad Murray, came out of the emergency room and announced, "Sorry kids, dad's dead," that Prince knew his father was gone.
"Nothing will ever be the same," the teenager told jurors.
He said while his younger brother doesn't totally realise the loss, his sister has had the hardest time of them all and he has had many sleepless nights since his father died four years ago. His voice wavered and tears formed in his eyes, but Prince remained composed as he publicly recounted for the first time what he saw the day his father died.
The retelling of the scene in Jackson's bedroom came after nearly an hour of Prince describing happier times, showing photos of him and his sister when they were younger and a series of videos of the children filmed by their father.
He testified in a lawsuit accusing concert promoter AEG Live LLC of negligently hiring Murray, who was later convicted of involuntary manslaughter for giving Jackson an overdose of the anaesthetic propofol.
AEG denies it hired the physician or bears any responsibility for the entertainer's death.
