Jackson Doc on the Move Again as Investigation Continues With State Attorney, DEA's Help

LAPD confirms DEA has come on board; a day after getting his impounded vehicle back, Dr. Conrad Murray no longer at L.A. condo

Federal agents and state officials are on board as the investigation into Michael Jackson's sudden death continues.

Los Angeles police on Thursday confirmed reports that the Drug Enforcement Administration has joined the investigation, with an LAPD spokeswoman telling E! News that there's nothing she could divulge about the collaboration at this point.

The L.A. County Coroner's Office confiscated a number of controlled substances from Jackson's rented Holmby Hills mansion Monday as part of the ongoing LAPD case. The DEA's diversion control program, which also assisted in various investigations related to the death of Anna Nicole Smith, regulates controlled pharmaceuticals.

California Attorney General Jerry Brown tells the L.A. Times that the Bureau of Narcotic Enforcement has also come onboard and will be utilizing the state's Controlled Substance Utilization and Evaluation System (CURES) to examine the prescription-drug aspect of the case.

The database, also used in the Smith case, holds the name of every doctor authorized to prescribe medication in the state, as well as a record of all prescriptions.

"If it's about doctors, drugs and patients or anything that touches that, it's in our database," Brown said. "We've been in touch with the LAPD and I've talked to Chief [William J.] Bratton."

As part of the probe, the LAPD has been interviewing doctors in connection with the various meds found in Jackson's possession.

Also interviewed was Dr. Conrad Murray, who apparently isn't one for sitting still for too long.

The privately hired cardiologist, who discovered Jackson unconscious last week and aided in paramedics' attempts to revive the singer, appears to no longer be staying at his L.A. condo, a couple of days after law-enforcement activity was detected outside.

Murray's BMW, which was impounded as evidence last Thursday following Jackson's death and returned to him Tuesday, is still parked outside and has not been driven.

Miranda Sevcik, spokeswoman for Murray's attorneys, tells E! News she couldn't speak to Murray's whereabouts.

Attorney Matt Alford told us on Monday that Murray, who was interviewed by authorities over the weekend, was "free to travel" and had been staying in L.A. voluntarily.

According to Murray's legal camp, the Nevada-based doctor is not considered a suspect and he is freely cooperating with the investigation. Murray has denied injecting Jackson with Demerol before he died or prescriping the 50-year-old artist either Demerol or OxyContin.
