Coroner's official serves subpoena to Jackson doc

BEVERLY HILLS, Calif. — A Los Angeles coroner's official has visited the office of Michael Jackson's dermatologist to serve a subpoena seeking additional medical records.

Assistant Chief Coroner Ed Winter went to Arnold Klein's Beverly Hills office around midday Tuesday.

Speaking to a throng of reporters outside the office, he said Klein had been cooperating in the investigation. Craig Harvey, the coroner's chief of operations, says it's the second time coroner's investigators have served Klein a subpoena.

They are focusing on the role drugs played in causing Jackson's death.

Klein has recently given TV interviews saying he sedated Jackson for medical procedures. He denied ever giving the pop star an unnecessary dose of drugs.
