According to the Times, Dr. Conrad Murray said he'd been treating Jackson's insomnia with 50 milligrams of Propofol every night for the previous six weeks. However, the doctor claimed he was worried Jackson was becoming dependent on the drug and tried to reduce the dosage.

On the day Jackson died, Murray had tried giving Jackson valium followed by lorazepam and midazolam to help him fall asleep. At 10:40 a.m. Jackson was still awake and demanded Propofol from Murray. The doctor then injected Jackson with the powerful anesthetic. Murray left Jackson to sleep and went to make several phone calls. When the doctor returned, he found Jackson wasn't breathing.

According to the LA Times, Murray acknowledged to police he gave Jackson Propofol, but investigators have not been able to find evidence that he had purchased, ordered or obtained the medication under his medical license or Drug Enforcement Administration tracking number.

Eight bottles of Propofol were found in Jackson's house along with other vials and pills that had been prescribed by Dr. Murray, Dr. Arnold Klein and Dr. Allan Metzger.

Dr. Murray, who accompanied Jackson to the hospital but refused to sign the death certificate, could face involuntary manslaughter charges for giving Jackson Propol outside of the safety of a hospital setting.

X17online was the first to report that Jackson had been rushed to the hospital, and as you can see in these pictures and video, it's clear that Jackson wasn't breathing at the time EMTs were called.
