Judge in Michael Jackson death trial chastises doctor for "horrific violation of trust"

(CBS/AP) LOS ANGELES - Dr. Conrad Murray was sentenced Tuesday, three weeks after a jury convicted the cardiologist of involuntary manslaughter in the death of Michael Jackson. Murray sat stoically as the judge chastised him for a "horrific violation of trust" in caring for the pop star.

"Dr. Murray created a set of circumstances and became involved in a cycle of horrible medicine," Superior Court Judge Michael Pastor said. He called the heavy use of propofol "medicine madness, which violated his sworn obligation, for money, fame prestige and whatever else may have occurred."

Pastor said one of the most disturbing aspects of Murray's case was a slurred recording of Jackson recovered from the doctor's cell phone.

"That tape recording was Dr. Murray's insurance policy," Pastor said. "It was designed to record his patient surreptitiously at that patient's most vulnerable point."

Murray was convicted of involuntary manslaughter after a six-week trial that presented the most detailed account yet of Jackson's final hours but left many questions about Murray's treatment of the superstar with an operating-room anesthetic as he battled chronic insomnia.
