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 . `` Perfect storm '' of drugs killed Jackson , sleep expert says . 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 could n'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 wo n'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 .
