Has a new document emerged suggesting that the late Michael Jackson may have once consumed up to 10 or more Xanax pills every night?

Citing a confidential document from 2004, CNN.com reports that Jackson took the drug, commonly used for panic disorder, and that he may have asked employees to get the prescription pills under their names.

The document is said to be from the Santa Barbara County Sheriff's Department stemming back from interviews with two of Jackson's former security guards that were conducted before the star's 2005 molestation trial, says CNN.com. Jackson was acquitted in that case after a 14-week trial.

In the document, one staffer was quoted as saying, "Jackson was doing better because he was down from 30 to 40 Xanax pills a night," according to CNN.

Another staff member was also reportedly documented saying he had picked up medication for Jackson in other people's names. CNN reports that five doctors (from California, New York, and Florida) were listed in the document.

In the document, one guard described Jackson as being "out of it and sedated" after leaving doctors' offices, reports CNN.

CNN reports that the guard who provided officials with most of the information in the document told officials that he quit after Jackson "fell on his face" in a hotel room.

Meanwhile, ET has learned that doctors have been subpoenaed in the death investigation of the King of Pop.

Authorities are waiting toxicology results to determine what caused Jackson's death. The pop icon passed away suddenly on June 25 at the age of 50.
