Michael Jackson's personal doctor has been charged with involuntary manslaughter for causing the pop singer's death.

The charge comes more than seven months after the 50-year-old entertainer's sudden death last year on June 25.

Following an exhaustive investigation, prosecutors in Los Angeles said Murray "did unlawfully and without malice" kill Jackson.

The Los Angeles coroner's office had earlier ruled Jackson's death a homicide by an overdose of drugs.

Murray, a cardiologist, has admitted administering the powerful anesthetic propofol to try to help Jackson sleep.  The prosecutor accuses the doctor of failing to use proper caution in providing the drug to the singer.

Propofol is supposed to be administered by an anesthesia professional, and only under hospital conditions.

Murray insists he did nothing wrong, and he has pleaded not guilty in court in Los Angeles.  The charge against him carries a possible term of four years' imprisonment.

Jackson hired Murray last May as he prepared for a series of comeback concerts in London.

Jackson's family - his parents, his brothers and sister - showed up at the Los Angeles courthouse for Monday's hearing.   His father, Joe Jackson, said  they were "looking for justice.".
