Conrad Murray, the doctor convicted of killing Michael Jackson, was released from jail today (October 28) in Los Angeles.

Murray was sentenced for four years in November 2011 for the involuntary manslaughter of the pop singer. The former cardiologist was given the maximum jail term after being found guilty of administering his patient with a lethal dose of the anesthetic Propofol as a sleep aid. He has served nearly two years of that sentence, Billboard reports.

Murray’s license to practice medicine has been suspended or revoked in three states, however reports have suggested that he will look to return to medicine. He is also reportedly looking to hire a publicist.

Murray is appealing his conviction, although an appeals court has questioned whether it should hear the case. His lawyer Valerie Wass has argued that his appeal should not be dismissed because it could alter his overall sentence, and reduce some of the stigma his conviction has caused.

A recent court case surrounding a lawsuit filed by Jackson’s mother against promoters AEG Live ruled that Murray was not unfit or incompetent to serve as Jackson’s tour doctor earlier this month. Katherine Jackson had argued that the promoters were negligent in hiring Murray as the singer’s doctor while he was rehearsing for his string of dates at London’s O2 Arena. However, the panel said it did not condone the physician’s conduct. Katherine Jackson will reportedly appeal the verdict.
