Dr. Conrad Murray acknowledged giving Jackson the drug propofol in a police interview two days after Jackson's death June 25, and according to a police affidavit made public by a Las Vegas judge, Los Angeles police and federal drug agents subsequently worked to connect the doctor to drug bottles found in the pop icon's rented Los Angeles mansion. During a July raid on the cardiologist's Las Vegas medical office, investigators found a receipt showing that a local pharmacy, Applied Pharmacy Services, had shipped quantities of the drug to Murray in May, when he was living in Los Angeles and working full time for Jackson, according to the affidavit. The lot numbers on the bottles in Jackson's house matched those sold to the company by drug manufacturers, according to the affidavit. Investigators have said in other court documents that Murray is the target of a manslaughter investigation, but prosecutors have not filed charges against him. The physician told police Jackson was dependent on propofol to sleep and that he was trying to wean the singer off the drug. The court papers were released after attorneys for media outlets, including the Los Angeles Times, petitioned the court.
