LOS ANGELES (AP) -- The coroner's chief toxicologist says the powerful anesthetic propofol was found in Michael Jackson's blood, urine and liver when he died.
Witness Dan Anderson testified Thursday at the involuntary manslaughter trial of Dr. Conrad Murray.
Anderson says Jackson showed no signs of opiates or the painkiller Demerol.
He says drugs detected in significant amounts were propofol, lidocaine and lorazepam, a sedative that Murray said he gave to try to get Jackson to sleep before he administered propofol.
Anderson says lorazepam was found at the high therapeutic level, but he did not characterize the amount of propofol.
Authorities say Jackson died of acute propofol intoxication combined with other sedatives administered by Murray, who has pleaded not guilty
