July 7, 2009 (ABC News) -- Both of pop superstar Michael Jackson's arms were scarred with track marks, investigators probing his death say, and the marks are consistent with the finding of the potent sedative propofol (trade name Diprivan) in his home -- a drug that is increasingly at the center of their probe into what caused Jackson's death, ABC News has learned.
The probe is being led by the Los Angeles Police Department in cooperation with the Drug Enforcement Administration. The California Department of Justice has offered technical support in terms of its powerful searchable data base of patient information that includes drugs, doses, the doctors that administered them and the patients that received them.
Prescription medications were found inside Jackson 's $100,000 per month rental home that included ones in his name and ones in other names, including ones that appeared to investigators to be aliases. The medications had been prescribed by multiple doctors.
Jackson was addicted to the analgesic Demerol and to Oxycontin, investigators have told ABC News, and took the drugs daily. Medical experts have reported propofol "blocks out the world."
