Prince Jackson, the eldest child of the late King of Pop, Michael Jackson, testified today in the wrongful death trail the Jackson family filed against entertainment company AEG Live LLC.

The 16-year-old delivered a heart-wrenching testimony, in which he described his famous father’s final moments. "My dad was hanging half off the bed, his eyes rolling back in his head," Prince said, as reported by, The New York Daily News . "My sister came upstairs, but we kept pulling her downstairs. She was screaming the whole time saying she wants her daddy."

The teenager said that he and his siblings were in tears by the time an ambulance arrived at their Los Angeles home. All Prince could think to do to comfort his sister, Paris, was to tell her repeatedly that "angels were watching over" their father.

Jackson’s son offered details about the “Thriller” singer’s relationship with Dr. Conrad Murray, AEG Live CEO Randy Phillips, and his manager, Dr. Tohme Tohme. Prince recalled phone conversations Jackson would have with Phillips and Tohme that would leave him visibly upset.

"He would cry sometimes after he got off the phone," Prince said. "He would say, 'They're going to kill me. They're gonna kill me.'"

Prince also shed light on a possible altercation between Phillips and Murray the night before Jackson’s death. The teenager said he remembers seeing the two men in what appeared to be a heated discussion, though he could not quite make out what they were saying.

"He was grabbing his elbow," Prince said of Phillips’ actions toward Murray, according to CNN . "It looked aggressive to me. He was grabbing by the back of his elbow and they were really close and he was making hand motions."

The Jacksons, which include Katherine Jackson, Prince, Paris and Blanket, contend that AEG Live is responsible for the singer’s death because the company hired and paid for Dr. Murray to attend to the pop star. AEG Live contends that it was Michael Jackson who hired Murray, who was convicted of involuntary manslaughter, and controlled his treatment.

The trial, in its ninth week, is expected to last until August.
