The doctor, who was released from prison three weeks ago, having served half of his four-year sentence for involuntary manslaughter – began working for Jackson in 2006.
The 60-year-old, who proclaimed his innocence throughout his trial, has protested his innocence again in an interview with a UK newspaper.
‘I did not kill Michael Jackson. He was a drug addict. Michael Jackson accidentally killed Michael Jackson,’ he said.
According to Murray, he became concerned when he was hired to help 50-year-old Michael prepare for his This Is It come-back tour in 2009.
'I held his penis every night to fit a catheter because he was incontinent at night.’
‘He was in crisis at the end of his life, filled with panic and misery,’ the heart surgeon explained.
Describing how the pop legend was filled with physical and mental anguish by the pressures of the tour, he added.
‘By the end Michael Jackson was a broken man. I tried to protect him but instead I was brought down with him.’
Murray claims the singer had become paranoid, not allowing maids to launder his boxers fearing they would sell them.
Revealing that he was one of the few people the father-of-three trusted, he added.
‘You want to know how close we were? I held his penis every night to fit a catheter because he was incontinent at night.’
Murray claims that Michael was dependent on prescription drug propofol to help him sleep, suffering from chills, insomnia and mood swings, and reducing his 5”11 frame to just over 9 stone.
According to the doctor, the singer’s insomnia was due to withdrawal symptoms from prescription drug pethidine, which had been provided by another doctor without his knowledge.
Speaking about Jackson’s death on June 25, 2009, Murray insists that Jackson secretly injected himself with a lethal dose of propofol after Murray refused to give him the amount he wanted.
Murray has filed an appeal against his conviction.
