Michael Jackson's eldest son has told a jury of the agonising moments as medics tried to save the pop star's life, and testified that his father feared his punishing tour rehearsal schedule would "kill him".
Michael Joseph "Prince" Jackson Jr described the frantic efforts to revive the music legend to the jury in a Los Angeles courtroom.
He recalled how he knew there was trouble in the singer's rented mansion when he heard screaming upstairs and went into his father's bedroom. His father was lying 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 said he had died 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.
The re-telling 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.
Prince also recalled how his father wanted more time to rehearse and had several tense phone conversations with promoters of his This Is It shows that sometimes ended with his father in tears. The 16-year-old said his father remarked after one of the conversations: "They're going to kill me." He did not give further details.
The testimony came in a lawsuit claiming AEG negligently hired Conrad Murray, the doctor 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.
Prince is the first Jackson family member to testify during the trial, now in its ninth week. His cousins, TJ and Taj Jackson, who are Tito Jackson's sons, will also take the witness stand.
