Authorities investigating Michael Jackson's death alluded to the singer as an “addict” and were seeking evidence related to the powerful anesthetic propofol, according to search warrants released Thursday. The documents show investigators have cause to believe several California Business and Professions codes had been broken, including “excessive prescribing,” a misdemeanor punishable by a fine or imprisonment for up to 180 days. Los Angeles police and federal Drug Enforcement Administration agents spent much of Tuesday at the Las Vegas home and business of Jackson's personal doctor, Conrad Murray, who is the focus of a manslaughter investigation. The raids sought evidence supporting that charge, as well as code violations, including “prescribing to an addict” and “unprofessional conduct.”
