Investigative journalist Diane Dimond, who has been covering Michael Jackson news since 1993, reports from the ET set on the drugs that police found in the raid on Neverland back in 2003.

"I was there in 2003, and I wrote about it in [Be Careful Who You Love: Inside the Michael Jackson Case]. Now, it looks like Diprivan -- the drug that may have killed Michael -- may have been in his life for years," she says.

The journalist was also in the courtroom during Michael's 2005 molestation trial -- he was acquitted -- and saw a video of the search conducted by the Santa Barbara County Sheriff's Department. Diane goes on to say that back in 2003, sources told her that IV bags of a milky white fluid were discovered in one of Jackson's bathrooms.

"Diprivan has a milky appearance and, as ET reported earlier, that powerful anesthesia drug was allegedly found by police at the singer's L.A. home after he died," Diane says.

Other medications found during the Neverland raid included: a vial of Versed, a powerful sedative; a bottle of Alprazolam, the generic form of the anti-anxiety drug Xanax; a bottle of the painkiller Percocet; and a vial of the powerful painkiller Demerol.

Also during the search of Neverland, the police discovered that Michael had an overhead projector and a large screen in his bedroom, so he could watch movies in bed.

"I was at Neverland the day that the police were combing through Jackson's possessions, looking for evidence," Diane says. "Many sources revealed that the entrance to Michael's bedroom was guarded by laser beams so that he could be alerted when anyone was approaching."
