Michael Jackson's personal doctor, Dr. Conrad Murray, has been charged with involuntary manslaughter in the King of Pop's death.

In a statement issued today, the L.A. County District Attorney's office says Dr. Murray "did unlawfully, and without malice, kill Michael Joseph Jackson." Murray is set to be arraigned on the charges in Los Angeles later on today.

Jackson died last June after Dr. Murray administered him the powerful drug Propofol. The coroner listed acute Propofol intoxication as the cause of his death.

If found guilty, he could face up to four years in prison. He has entered a plea of not guilty.
