Officials investigate Jackson's doctors in star's death

Police and federal drug agents investigating the death of pop star Michael Jackson have seized documents and computer records from his doctor’s clinic as they narrow their focus in what could become a criminal probe.

Almost one month after the King of Pop died, investigators from the Drug Enforcement Administration and Los Angeles police yesterday raided the Houston clinic of Conrad Murray, the personal physician Jackson hired in May to look after him as he prepared for a series of comeback concerts in London.
