Jackson's death in June 2009 stunned the world, as did the ensuing investigation that led to Murray being charged in February 2010.
Murray told detectives he had been giving the singer nightly doses of propofol to help him sleep as he prepared for a series of comeback concerts. Propofol is supposed to be used in hospital settings and has never been approved for sleep treatments, yet Murray acknowledged giving it to Jackson then leaving the room on the day the singer died.
Murray declined to testify during his trial but did opt to participate in a documentary in which he said he didn't consider himself guilty of any crime and blamed Jackson for entrapping him into administering the propofol doses. His attorneys contended throughout the case that Jackson must have given himself the fatal dose when Murray left the singer's bedside.
In their sentencing memorandum, prosecutors cited Murray's statements to advocate that he receive the maximum term. They also want him to pay restitution to the singer's three children - Prince, Paris and Blanket.
It's unlikely that Murray can pay any sizable sum, including the $1.8 million cost of his funeral. He was deeply in debt when he agreed to serve as Jackson's personal physician for $150,000 a month, and the singer died before Murray received any money.
Prosecutors said the relationship of Jackson and Murray was corrupted by greed. Murray left his practices to serve as Jackson's doctor and look out for his well-being, but instead acted as an employee catering to the singer's desire to receive propofol to put him to sleep, prosecutors said.
"The defendant has displayed a complete lack of remorse for causing Michael Jackson's death," prosecutors wrote in a filing last week. "Even worse than failing to accept even the slightest level of responsibility, (Murray) has placed blame on everyone else, including the one person no longer here to defend himself, Michael Jackson."
Murray's attorneys are relying largely on 34 letters from relatives, friends and former patients to portray Murray in a softer light and win a lighter sentence. The letters and defense filings describe Murray's compassion as a doctor, including accepting lower payments from his mostly poor patients.
"There is no question that the death of his patient, Mr. Jackson, was unintentional and an enormous tragedy for everyone affected," defense attorneys wrote in their sentencing memo. "Dr. Murray has been described as a changed, grief-stricken man, who walks around under a pall of sadness since the loss of his patient, Mr. Jackson."
