LOS ANGELES, California (CNN) - Singer Michael Jackson took more than 10 Xanax pills a night - asking his employees to get the prescription anti-anxiety medication and sleep aid under their names and personally traveling to doctor's offices in other states to obtain them, said a confidential document from 2004 that CNN obtained Thursday.

The document from the Santa Barbara County Sheriff's Department contains confidential interviews conducted with two of Jackson's former security guards as officials prepared for Jackson's child molestation trial in 2005.

The singer was acquitted after the 14-week trial. But the information about the medication - and the lengths Jackson went to get them - add to a growing mountain of claims tying the insomniac singer to drugs in recent days.

Los Angeles Police Chief William Bratton said Thursday that detectives had spoken to a number of doctors who had treated Jackson over the years, and were looking into the singer's prescription drug history.

Doctors who did not cooperate with investigators received subpoenas, a source told CNN Thursday. If needed, authorities will issue more, the source said.

Jackson died on June 25. Authorities await toxicology reports from the coroner's office to determine the exact cause of death.
