Coroner Back At Arnie Klein's Office

An official from the L.A. County Coroner's office has just returned to Dr. Arnold Klein's office in Beverly Hills to retrieve more files in the Michael Jackson case.

Assistant Chief Coroner Ed Winter just told our photog he was there for more MJ medical files.

UPDATE: Winter has left, but wouldn't comment on whether or not anything was taken from Klein's office.

Dr. Klein's lawyer briefly addressed the press after Winter left, saying a subpoena was served but Winter wasn't looking for documents -- instead he wanted more information about docs the coroner's office had already seized. Dr. Klein's lawyer said they cooperated fully with Winter's requests.
