The Los Angeles County Coroner's Office investigators returned to Michael Jackson's Holmby Hills home Monday -- along with LAPD detectives -- and brought back evidence to aid their investigation of the musician's death, the coroner's office confirms to Usmagazine.com.
Lt. Fred Corral, who supervises coroner investigators, said they may have visited the home where Jackson fell ill on Thursday to "look for medications or talk to witnesses."
Although some reports claim Jackson may have overdosed on Demerol, Corral told Us that it is routine to follow up autopsies with on-site investigations.
"It's nothing unusual," he said. "Remember, the whole purpose is to determine the cause of death."
The coroner's office completed its autopsy of Jackson on Friday and found no trauma or indication of foul play. Although the autopsy confirmed that he had been taking prescription medication, officials said they are waiting for toxicology results -- which take several weeks -- to reveal more about what killed Jackson.
Earlier Monday, the coroner's office debunked a so-called "leaked autopsy" report in a British tabloid. "It's all bull," assistant chief coroner Ed Winter told Us.
