"Once I was comfortable and I moved away from his bedside, yes, I stayed in the adjacent chamber and I used the phone, et cetera, et cetera, but I was not worried about him. Actually, I was already packed and ready to go home."
But at some point around 11 a.m., Murray apparently realized his patient was not breathing.
Murray: Just happened to be there at the end
"I have taken the front of the storm for the entire life of a man 50 years old, who has had a monumentally destructive, painful life that has been so damaged it is of huge proportions," Murray told Lemon.
"It is in terms so humongous that for 50 years of pain that he (Jackson) has lived and I did not do him for all of that," Murray said. "All of the mishaps that he has encountered in life seem to trickle down on me and I think that is the definition of a scapegoat. Nobody has taken any responsibilities for anything that they may have done to this man but, because I was in the wrong place at the wrong time, then here I am."
"You just happened to be there at the end," Lemon said.
"Yes," replied Murray.
"Conrad Murray, as you sit here now in jail, do you believe you are innocent?" Lemon asked.
"Absolutely," Murray said. "No doubt."
"He's never wavered," his lawyer Valerie Wass added.
"Why am I innocent?" Murray continued. "Because I did nothing wrong and all I tried to do was to help a friend who I encountered in a devastated state and I tried to do everything possible to help my friend. I have been called names and who knows what. Nobody else was there at that time and I can say with the effort that I made I could've suffered a cardiac arrest myself. It was not an easy task but I never gave up on my friend -- never did."
Wass then stopped Murray from saying more that might relate to his criminal case, which she is appealing.
Murray: My trial was not fair
"I believe I was not given due process. I think the judge was not impartial. I think the district attorney did something that was so absurd. He altered evidence in open courtroom. Could you imagine that?" he told Cooper.
The evidence was prosecution exhibit 30, an empty propofol bottle that was allegedly placed in a makeshift IV configuration. Deputy District Attorney David Walgren pulled an unused tab on the bottle that was intended to hold the bottle on a stand. When investigators found it, it was not pulled.
"If I had to do this again, that's the one thing I would never do," Murray said. "I would never sit quietly in the courtroom and have a district attorney tear open and destroy the integrity of evidence when there was no reason to do that. That was not the only time. There were so many issues of irregularity and obstruction of justice on his part."
Murray: Michael was my great friend
Murray talked about his relationship with Michael Jackson in the last months.
"I've lost a friend, a great friend, a man who was imperfect like all of us are," he told Lemon. "He has had his dark sides and he has had his good sides and I've known them both."
His role in the friendship was to bring Jackson peace, Murray said.
