Conflicting reports about the nature of Michael Jackson's death swirled Wednesday, with TMZ reporting that the LAPD is treating it as a homicide, despite a denial from an official spokeswoman to other media outlets.
TMZ cited multiple sources Wednesday who claimed that the investigation is homing in on Dr. Conrad Murray, with evidence pointing to the anesthesic Propofol as the primary cause of the King of Pop’s death.
But LAPD officer Tenesh Dobine told Access Hollywood that the investigation was still "ongoing" and did not know where TMZ obtained their information. A media relations spokeswoman for the LAPD offered similar information to NBC news, saying Murray had not been served any subpoenas or search warrants.
Murray is believed to be the person who administered the drug to Jackson, who died at the age of 50 on June 25, says the website. According to TMZ, the evidence includes various items found in his home, including drug paraphernalia.
Jackson, who died June 25, had a well-known history of using prescription medications, especially painkillers. Following his death, Cherilyn Lee, a registered nurse who had worked for Jackson, told the Associated Press she repeatedly rejected his demands for the potent anesthetic Diprivan, also known as Propofol.
Police towed a doctor's car from Jackson's home – believed to belong to Murray — hours after he died, and said later it could contain medication or other evidence. Los Angeles Coroner officials also said Jackson was taking prescription medication but declined to elaborate.
