Input: A potent and lethal dose of propofol was the likely factor that induced the death of  pop king Michael Jackson  his personal doctor Conrad Murray told the authorities  the Los Angeles Times reported Monday.
 In a search warrant affidavit declassified in Houston  Murray told the Los Angeles Police Department (LAPD) that he had kept giving Jackson 50 milligrams of propofol every night for about six weeks in an effort to treat his insomnia.
 Fearing an addiction was taking root in Jackson  Murray began to wean him off the drug by reducing the daily dosage by half and mixing it with two other sedatives  lorazepam and midazolam. From June 23 on  he administered only two medications excluding the propofol.
 Two days later  Murray tried to help Jackson go into sleep  also without using propofol. From 2 a.m. (0900GMT)  he injected lorazepam intravenously twice. He then gave the pop star midazolam since Jackson was still awake  the report said.
 He used various drugs before 10:40 a.m. (1740GMT) when he injected 25 milligrams of propofol after Jackson insisted in getting the drug.
 Murray has already admitted to obtaining and administering propofol on Jackson the morning he died in an interview with LAPD detectives before the court document was made known. Making telephone calls to his Houston office and family members  Murray left Jackson alone under the influence of the drug  only found that Jackson stopped breathing when he was back. He performed Cardiopulmonary Resuscitation  and one of Jackson's aide called 911  but to no avail. Jackson was pronounced dead later after he was rushed to the Medical Center of University of California  Los Angeles.
 An investigation is still underway  aiming to make clear the role propofol played in Jackson's death and whether there is any wrongdoings on the part of Murray.
