Jackson's Maid -- He Binged On Drugs

One of Michael Jackson's former housekeepers told law enforcement the singer was often in such bad shape from drugs, his eyes would roll back in his head.

We've obtained documents from the Santa Barbara County Sheriff Department's 1993 investigation into allegations of child molestation. Kristina Fournier told deputies back then ... she saw syringes while she was employed at Neverland. Deputies asked her if she ever saw Jackson inject himself with a hypodermic needle -- she said no.

Fournier told deputies she was aware Jackson was under the influence of drugs and "under a doctor's care." Fournier said she saw doctors "come and go" at Neverland.

And Fournier said, on the subject of Jackson's drug addiction, "I think he had good periods and bad periods, and when he had a bad period, he had a bad period. Then he would get off (referring to drugs) and then it would start again."

Fournier said it was "well-known" among the Neverland staff that Jackson had a drug problem -- "Yes, and people would say, his eyes were rolling in the back of his head and he wouldn't know what he was talking about."
