*Prosecutors are expected to play for jurors a police interview conducted with Dr. Conrad Murray during which he lays out his version of events in the final hours of Michael Jackson’s life.

The more-than two hour interview has never been played in public before, nor has a transcript of its contents been released reports the AP. In it, Dr. Conrad Murray details his treatments on Jackson in the hours before the singer’s death, including his administration of the anesthetic propofol.

The interview was conducted by two Los Angeles police detectives, one of whom, Scott Smith, will introduce the interview for jurors during the trial’s ninth day on Friday, prosecutors have told a judge.

The interview will be played after defense attorney J. Michael Flanagan finishes cross examination of coroner’s toxicologist Dan Anderson.

On Thursday, Anderson told jurors that propofol was found in various parts of the singer’s body, his blood and urine during an autopsy. The amounts found led coroner’s officials to conclude that Jackson died from acute propofol intoxication, with other sedatives administered by Murray contributing to the singer’s death.

Defense attorneys contend Jackson gave himself the lethal dose after Murray left the room. Flanagan attempted Thursday to get Anderson to say that high levels of the sedative lorazepam found in Jackson’s stomach meant that he swallowed the drug himself. Anderson told jurors he couldn’t determine that based on the information he had.

Also on Thursday, lead defense attorney Ed Chernoff attacked the credibility of a coroner’s investigator who collected evidence at the house on the June 25 and June 29, 2009 searches of Jackson’s home. Chernoff noted that investigator Elissa Fleak had moved items in the room and failed to note in a report until nearly two years after Jackson’s death that she had found a bottle of propofol inside an IV bag.

Jackson’s bodyguard Alberto Alvarez described the bottle in the IV bag during testimony last week and in January during a preliminary hearing, leading Chernoff to question whether Fleak had added the detail to match Alvarez’s description. Fleak had photographed the bottle and IV bag together, but with the container placed outside the bag.

Fleak denied any wrongdoing, and denied Chernoff’s contention that she had made “a substantial number of mistakes.”

The investigator also acknowledged that she had handled a syringe without gloves, leaving a thumbprint on the item.

Walgren attempted to deflect the criticism, asking the investigator whether she had conducted a perfect investigation. No, she replied.

Murray has pleaded not guilty to involuntary manslaughter in the death of Michael Jackson and faces up to four years behind bars and the loss of his medical license if convicted.
