AP Photo/Houston Chronicle, Pool PhotographerFederal drug agents are onboard and 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 a 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 prescription drugs 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.
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 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.
