Been loathe to delve into the Michael Jackson mess, but apparently the L.A. County Coroner just ruled Jackson's death a homicide.The document unsealed Monday allowed officials to raid the Houston offices and storage facility of Dr. Conrad Murray last month. According to the warrant, Murray, Jackson's personal physician, had been treating the singer for insomnia with the sedative for six weeks. According to the document, Murray said he had been trying to wean Jackson off the powerful sedative by using smaller doses in combination with the sedatives lorazepam and midazolam.On the morning Jackson died, Murray said he tried to induce sleep without using propofol, starting first with valium at 1:30 a.m. When Jackson was still awake at 2 a.m., Murray injected Jackson with lorazepam, then injected him with midazolam at 3 a.m. Murray told police he administered several other drugs over the next few hours.By 10:40 a.m., Jackson, still unable to sleep, urged Murray to give him propofol. Murray said in court documents that he administered 25 milligrams of the drug at that time, then left Jackson alone under the influence of the drug to make phone calls to his Houston office. When he returned, Jackson was not breathing. He performed CPR while a member of Jackson's staff called 911. The singer was rushed to UCLA Medical Center where he was declared dead sometime later.A sad, strange case indeed.
