Jurors Hear About Drugs Found In Michael Jackson's System

LOS ANGELES (CBS) — Jurors Thursday heard about drugs that were found in Michael Jackson's body and bedroom after the pop star's death in 2009.

Dr. Conrad Murray is accused of involuntary manslaughter in Jackson's death and has pleaded not guilty.

Elissa Fleak, a coroner's investigator,  took the stand Thursday. Fleak acknowledged that she made several mistakes while collecting evidence, including medication, from Jackson's bedroom after his death.

Fleak was assigned to the investigation on June 25, 2009, when Jackson died and went to his rented mansion to collect evidence. Four days later, after Murray had talked to police, she returned to follow leads the doctor had provided, including a description of medications hidden in a closet.

Fleak admitted to moving evidence and failing to find a vile of propofol hidden in a saline bag until 2011. Murray's fingerprints were found on that bottle.  Fleak's fingerprints were also found on medications and equipment in the singer's bedroom.

Fleak later said that no investigation was perfect.

The coroner's chief toxicologist, Dan Anderson, also took the stand Thursday, testifying that propofol was found in Jackson's blood, urine and liver when he died. He did not specify how much of the drug was found in Jackson's system.

Anderson also told jurors that lidocaine and lorazepam, a sleep aid, were also found in the singer's body.

He said Jackson showed no signs of opiates or Demerol, a painkiller.

Jackson died at age 50 from an overdose of  propofol. If convicted, Murray faces four years in prison.
