CONRAD MURRAY TRIAL: JACKSON’S FINGERPRINTS NOT ON ANY MEDICAL BOTTLES

None of the fingerprints on propofol bottles found in Michael Jackson's bedroom or in his doctor's possession belonged to the king of pop, sources close to the investigation told ABC News.

That revelation might deal a crippling blow to Dr. Conrad Murray's defense theory that Jackson himself took a lethal dose of propofol and the sedative lorazepam without Murray's knowledge, creating a "perfect storm in his body that killed him instantly." Murray is on trial for Jackson's death and could face four years in prison if convicted of involuntary manslaughter.
