Police have long believed Dr. Conrad Murray administered Propofol, a potent anesthesia that should never be found outside a hospital, to Michael Jackson.
They have also been operating under the assumption that this killed him.
Well, there's a good reason police believe Murray gave the star the drug. It turns out he admitted doing so two days after Jackson's death back on June 25.
Dr. Conrad Murray told the LAPD he administered Propofol to the music icon hours before he died. This is according to multiple law enforcement sources.
Murray gave Jackson an IV drip of the powerful anesthesia.
Police believe Murray simply wasn't paying attention when the star's heart stopped beating, thus accounting for the timeline gap in between when the coroner's office believes Jackson flatlined and when the 911 call was placed.
One theory? Dr. Conrad Murray fell asleep while the drug was being administered and awakened to find Michael Jackson dead of cardiac arrest. The singer died by the time paramedics arrived, though Murray did not let them call it there.
An IV drip of Propofol allows for a constant, steady infusion of the drug during a period of time determined by the trained professional administering it.
Again, this is supposed to take place in a hospital.
Moreover, it is considered reckless in the medical community for a doctor to administer an IV drip of Propofol without the patient being monitored by an EKG, which monitors the patient's pulse. No EKG was found in Michael's house.
Another device called a pulse oximeter is used to determine the oxygen saturation in the patient's blood. If the patient's breathing slows to dangerous levels, an alarm will alert the treating physician. No oximeter was found in the house.
No one knows precisely why the drug was administered.
If the above is all true, however, we suspect it is only a matter of time before Dr. Conrad Murray faces the music, possibly even manslaughter charges.
