LOS ANGELES (AP) - A lawyer for Michael Jackson's doctor is due in court to argue for the release of Conrad Murray on bail. Superior court Judge Michael Pastor planned to hear the request Friday in Murray's absence. The doctor remains jailed in solitary confinement after being sentenced to four years for his role in the superstar's death. Murray's lawyer says his client should be released on his own recognizance or on bail while his appeal  winds its way through the courts. But prosecutors have said that Murray was properly sentenced and would be a flight risk and a danger to the community if released. Murray was convicted Nov. 7 of involuntary manslaughter after a trial focusing on use of the anesthetic propofol. Jackson died of an overdose of the drug while in Murray's care.
