Michael Jackson feared for his life and felt that executives at AEG Live would kill him, Jackson’s son, Prince, testified during the pop icon's wrongful death trial in Los Angeles, according to the New York Daily News.

The Jackson family is seeking $40 billion from AEG Live, for Jackson’s premature death, blaming the event promotion company for hiring Conrad Murray, the doctor who was convicted of involuntary manslaughter for giving the artist an overdose of anesthetics.  

Prince, 16, took to the stand for the first time Wednesday, where he stated that Jackson had issues with AEG Live executives, and recalled seeing his father cry after a heated conversation with the concert show promoters.

“He would cry sometimes after he got off the phone,” Prince said, according to New York Daily News. “He would say, ‘They’re going to kill me. They’re gonna kill me.’”

Prince also claimed to have seen AEG Live chief Randy Phillips grabbing Conrad Murray in an aggressive manner.

“He was talking to Dr. Murray and he was grabbing his elbow and it looked aggressive to me,” Prince said, adding that he could not hear what was being said.

Talking about Jackson’s death and how it has affected the singer's children, Prince said his sister, Paris, who is currently in hospital following a suicide bid, was the most affected.

“Out of all my siblings, she was probably hit the hardest because she was my dad’s princess,” Prince said. “It really hurt her a lot. She definitely is dealing with it in her own way.”

Paris is currently said to have come to terms with her father’s death with the help of counseling in the hospital, according to British tabloid Mirror. A friend of the Jackson family told the tabloid that the hospital has provided the “the sanctuary she needed to unleash her grief.”
