Police have raided the Las Vegas home and office of Michael Jackson's personal physician as the probe into the pop star's sudden death focused increasingly on the doctor who was at his side when he died.
It was the second raid on Dr Conrad Murray in less than a week as officials seek evidence into the cause of the singer's sudden death by cardiac arrest on 25 June.
Dr Murray's lawyer said after the first raid last week that police and DEA agents were looking for "evidence of the offence of manslaughter."
Their probe now seems focused on Michael Jackson's use of prescription drugs, particularly the anesthetic propofol and Dr Murray's possible involvement in providing it.
Rusty Payne, a spokesman for the US Drug Enforcement Agency said federal agents and police entered Dr Murray's Las Vegas home and nearby office early on Tuesday morning looking for documents, but he declined to be more specific.
Last week's search at Dr Murray's office in Houston yielded information from a computer hard drive, billing and medical records, vials of medication, a Rolodex card and other objects, according to court documents cited in numerous media reports.
