Jackson's doctor negotiating surrender

The lawyer representing Dr. Conrad Murray, who cared for pop star Michael Jackson before his death, is negotiating the physician's surrender to Los Angeles authorities.

According to a statement issued Thursday, Ed Chernoff said he is in talks with the L.A. County District Attorney's Office for his client's surrender.

"When the agreement is complete, we will report further," Chernoff said.

Murray has yet to be charged with any crime related to Jackson's sudden death on June 25.

Jackson hired Murray, who has practices in Houston and Las Vegas, to serve as his personal physician in the run-up to his This Is It concert series in London, England. He died in Los Angeles just weeks before the first performance.

The subsequent police investigation into Jackson's death has focused on Murray's treatment of the performer and his decision to administer various medications, including propofol. Administered intravenously, the powerful anesthetic is typically used in hospitals to induce unconsciousness for surgery, but in Jackson's case, it was used as a sleep aid.

In August, the L.A. county coroner's office ruled the music icon's death was due to "acute propofol intoxication," with other sedatives also a contributing factor.

Murray, through Chernoff, has maintained that nothing he prescribed nor administered to Jackson should have caused the singer's death.
