LOS ANGELES - Los Angeles prosecutors on Monday plan to file a criminal case in the death of Michael Jackson which is expected to include a charge of involuntary manslaughter against the singer's personal doctor. The District Attorney's office said on Friday that details of the charges would be officially released on Monday and gave no further information. One source close to the case said Dr. Conrad Murray, who has been under investigation for months, would be charged with involuntary manslaughter. Late on Thursday an attorney for Murray, Ed Chernoff, said the doctor had agreed to surrender himself. Chernoff is expected to hold a news conference later on Friday. Murray was with Jackson when he died on June 25 and has admitted giving the 50-year-old singer a dose of the powerful anesthetic propofol to help him sleep. The Los Angeles coroner's office ruled that Jackson's death was a homicide, caused principally by propofol and the sedative lorazepam. A cocktail of other painkillers, sedatives and a stimulant were also found in his body. Murray, a cardiologist, has repeatedly insisted he did nothing wrong and has told investigators he was not the first doctor to give Jackson propofol, according to court records. Murray was hired in May 2009 to care for Jackson while the entertainer prepared for a series of comeback concerts in London aimed at reviving a career sidelined by his 2005 trial and acquittal on charges of molesting a 13 year-old boy. Jackson's sudden death prompted a worldwide outpouring of grief for the singer, who started his career as a child and whose 1982 album "Thriller" remains the world's best-selling album.
