Assistant Chief Coroner Ed Winter said outside the Beverly Hills office of Arnold Klein that the doctor had been cooperating in the investigation.
Craig Harvey, the coroner's chief of operations, said Klein had yet to provide some records, but his lawyers had said Klein would comply. Harvey would not specify what records were being sought.

In recent TV interviews, Klein said he had sedated Jackson for past medical procedures. He denied ever giving the pop star an unnecessary dose of drugs.
