A former patient of the doctor charged in Michael Jackson’s death told jurors the physician saved his life.

Robert Russell of Las Vegas lauded Dr. Conrad Murray’s treatment of him, but testified?on September 30?that his cardiologist became increasingly distant and hard to reach while working with Jackson.

Russell told jurors he couldn’t get answers about his treatment from Murray’s office on June 25, 2009 and demanded to speak to the doctor. The doctor left him a voicemail at 11:49 a.m.

Prosecutors are using records to show that Murray was on the phone in the moments before he realized Jackson was unconscious.

Russell told jurors Murray’s message seemed odd because the doctor said he was going on sabbatical, despite telling the salesman and his wife months earlier that he was going to work for Jackson.
