On Monday, an affidavit was unsealed in Houston, where a storage facility belonging to Murray was raided by police last month.
The document states lethal levels of powerful anesthetic Propofol were found in the King of Pop's bloodstream at the time of his death.
Murray allegedly told cops he had been treating Jackson for insomnia for six weeks before the singer's death, giving him 50 milligrams of Propofol every night using an intravenous line.
The doctor also reportedly tried to wean his famous patient off the drug by lowering the dosage to 25 milligrams and mixing it with other sedatives.
But Murray's lawyer insists integral parts of the affidavit are incorrect -- including claims that the medic left the star alone while he made phone calls on June 25, the night Jackson died.
In a statement, attorney Edward Chernoff says, "Much of what was in the search warrant affidavit is factual. However, unfortunately, much is police theory.
"Most egregiously, the timeline reported by law enforcement was not obtained through interviews with Dr. Murray, as was implied by the affidavit. Dr. Murray simply never told investigators that he found Michael Jackson at 11:00 a.m. not breathing. He also never said that he waited a mere 10 minutes before leaving to make several phone calls.
"In fact, Dr. Murray never said that he left Michael Jackson's room to make phone calls at all... We will not comment on the 'anonymous' law enforcement source that claims that Michael Jackson's death will be ruled a homicide. Most of the reports by 'anonymous' sources have been proven wrong. We will be happy to address the Coroner's report when it is officially released."
