Police on Tuesday conducted a new raid of a Las Vegas medical facility in their ongoing probe into the death of Michael Jackson, this time searching a pharmacy for documents and computer records.

Officials with the U.S. Drug Enforcement Agency, which is assisting Los Angeles police in their investigation of the pop star's sudden death on June 25, said agents conducted the raid at a business called Applied Pharmacy Services.

DEA spokesman Jose Martinez declined to say if the search was tied to Jackson's personal doctor, Conrad Murray, whose house and medical offices were raided last month in Houston and in Las Vegas. But Martinez did confirm that Tuesday's raid involves the probe into Jackson's death.

Jackson suffered cardiac arrest and died at age 50. Since then, numerous media reports have said investigators are focusing on his use of prescription drugs, particularly the powerful anesthetic propofol, and Murray's possible involvement in providing it.

On Monday, the Los Angeles County Coroner said it had completed its autopsy report on Jackson's body, but their findings remain under seal while police continue their investigation.
