Jackson Doc Charged With Involuntary Manslaughter

Dr. Conrad Murray.

The Los Angeles County District Attorney's office on Monday morning filed its long-awaited case against Conrad Murray, the Houston physician who was with Michael Jackson during the pop star's last hours in June.

Murray "did unlawfully, and without malice, kill Michael Joseph Jackson...in the commission of an unlawful act, not amounting to a felony; and in the commission of a lawful act which might have produced death, in an unlawful manner, and without due caution and circumspection," argues the District Attorney's office in a statement released Monday. Murray was charged with involuntary manslaughter and was expected to appear Monday afternoon for arraignment at the LAX courthouse.

If convicted Murray would face a maximum of four years behind bars. Deputy District Attorney David Walgren has been announced as the case's lead prosecutor.

Murray was with Jackson at the pop star's Holmby Hills home when he went into cardiac arrest on the morning of June 25, 2009. Murray is reported to have injected Jackson with the powerful drug propofol, which the county coroner's office cited as a factor in what it deemed was a homicide. Experts say the drug should only be administered in a medical facility.
