LAS VEGAS , Nevada -LRB- CNN -RRB- -- Police executed a search warrant at a Las Vegas pharmacy Tuesday morning in connection with the investigation into Michael Jackson 's death , a federal drug agent said . A Las Vegas pharmacy was searched Tuesday in connection with Michael Jackson 's death . Applied Pharmacy on Flamingo Road in Las Vegas sold the anesthetic propofol to Dr. Conrad Murray , Jackson 's doctor , a source familiar with the investigation said . Another source close to the investigation said last month that Murray , a Texas-based cardiologist , is said to have given Jackson propofol , commonly known by the brand name Diprivan , in the 24 hours before he died . The search of Applied Pharmacy came two weeks after searches of Murray 's home and clinic in Las Vegas . The search warrant served Tuesday authorized investigators to seize documents -- both on computers and paper -- related to the Jackson investigation , DEA Assistant Special Agent in Charge Mike Flanagan said . The warrants used for those earlier searches , which were filed in a Clark County , Nevada , court , imply that investigators looking into Jackson 's death believe that the singer was a drug addict . The warrants , signed by District Judge Timothy Williams and given to CNN by Las Vegas affiliate KTNV , say that `` there is probable cause to believe '' that the searches would uncover evidence at Murray 's home and office of excessive prescribing , prescribing to an addict , prescribing to or treating an addict and manslaughter . They cite `` probable cause to believe '' that the premises contained `` records , shipping orders , distribution lists , use records relating to the purchase , transfer ordering , delivery and storage of propofol -LRB- Diprivan -RRB- . '' Murray was with Jackson on June 25 when he was rushed to UCLA Medical Center in Los Angeles and when he was pronounced dead , according to Murray 's lawyer . A source involved with the inquiry into Jackson 's death has said that investigators found numerous bottles of prescription drugs in his $ 100,000-a-month rented mansion in Holmby Hills , California . The items taken from Murray 's home included copies of his computer and cell phone hard drives . They were to be turned over to the Los Angeles Police Department , which is leading the investigation into Jackson 's death at age 50 . A `` thorough and comprehensive '' report into the death of Michael Jackson is complete , the Los Angeles County coroner 's office said Monday , but police have requested that the report not be released because of the ongoing investigation . The coroner 's office said it would abide by the request that `` the cause and manner of death remain confidential '' and referred all questions to the Los Angeles Police Department .
