Los Angeles (CNN) -- Michael Jackson's oldest son disputed Dr. Conrad Murray's claim, given in his police interview, that the doctor comforted him and his siblings in the emergency room after they learned their father was dead, according to a Jackson family member who was with the children that day.
Prince Jackson told his family that Murray's account played in his involuntary manslaughter trial this week was not true, Trent Jackson, the nephew of Katherine and Joe Jackson, said Thursday.
Jackson family members were upset that jurors may sympathize with Murray because of perceived compassion for the children that day, Jackson told CNN.
"I hugged them all, gave comfort to Paris, comfort to Prince, comfort to Blanket, which is the last little guy, because whenever they were sick, they would always ask for Dr. Conrad," Murray told detectives two days after Jackson's death in 2009.
Trent Jackson, who drove Katherine Jackson to Ronald Reagan UCLA Medical Center, where doctors were trying to revive her son, said Murray did not have a conversation with Paris Jackson, the 12-year-old daughter, as he told police.
"She asked me, 'Dr. Murray, you said you save a lot of patients. You know, you save people with heart attacks, and you couldn't save my dad," Murray told detectives. "I said, 'I tried my best.' And she said, 'I know that, Dr. Murray. At least I know. I know you tried your best. I know you tried your best, but I'm really sad. You know, I will wake up in the morning, and I won't be able to see my daddy.'"
Prince, Paris and Blanket Jackson were initially kept in an SUV outside of the emergency room after they followed the ambulance carrying their father to the hospital, Trent Jackson said. Frank Dileo, who was Michael Jackson's manager, later escorted them inside after their grandmother arrived, according to Trent Jackson.
Murray never spoke to Michael Jackson's mother at the emergency room, contrary to his statement to police, Trent Jackson said.
While the truthfulness of Murray's interview is a major issue in the trial, it is not expected that Michael Jackson's 14-year-old son Prince will be called to testify, the relative said. Katherine Jackson, who has custody of the children, is opposed to any of them being called as witnesses, he said.
Prosecutors are near a conclusion to their direct presentation in Murray's trial, but rebuttal witnesses could be called next week after the defense rests its case.
