Emotions were running high on the 10th day of the trial. Michael Jackson's mother Catherine Jackson left the courtroom just before the state introduced autopsy pictures of her son's naked and lifeless body.

Then, the jury listened to more of the LAPD interview where we hear Dr. Conrad Murray explaining himself to detectives.

He said, over the course of caring for Jackson, he tried multiple drugs to help the singer sleep, from Valium to Lorazipan.

LAPD: Did that help him relax? Murray: No, he complained that he would have to cancel shows. He was still wide awake, no change.

So the doctor made a change to help his patient, so he says.

Murray: It was just a medicine he was familiar with. Detective: What was it? Murray: Propofol. Detective: Propofol.

Murray maintains he was in the bathroom when Jackson gave himself the deadly dose of Propofol. But on Tuesday, the Deputy Medical Examiner testified that it is just not possible.

On the stand, Dr. Christopher Rogers said, "You would have to assume Mr. Jackson woke up and although he was under the influence of Propofol and other sedatives, he was able to somehow administer Propofol to himself and then he stops breathing. And all this takes place in a two-minute period of time."

Rogers says it is not enough time especially considering Jackson's injection sit for the drug was just under the knee. "When Propofol is injected into the leg, it takes a while to get to the brain," testified Rogers.

Back to the LAPD interview and Murray tells detectives what happened when he came back from the bathroom.

Murray: I came back to his bedside and I was coming to the sense that he wasn't breathing.

Even though his patient was in dire need, Dr. Murray did not call 911.

His reason?

Murray: To speak to a 911 operator would be to neglect him.

The state says Dr. Murray did indeed neglect his patient to the point of involuntary manslaughter. Murray faces up to four years in prison if convicted.
