Autopsy doctor says Jackson may not have caused his own death

LOS ANGELES - Michael Jackson probably did not give himself the powerful anesthetic propofol that caused his death in 2009, the doctor who performed the singer's autopsy testified on Tuesday.

Dr Christopher Rogers told jurors in the manslaughter trial of Dr Conrad Murray that he determined Jackson's death was a homicide.

Murray has denied involuntary manslaughter but has admitted giving Jackson the anesthetic used for surgery as a sleep aid. However, his attorneys have claimed that Jackson caused his own death by giving himself an extra dose when Murray was out of the singer's bedroom on June 25, 2009.
