The agency is reportedly seeking Jackson's medical records.

Dr. Klein is allegedly under investigation for over-prescribing medication to Jackson and prescribing drugs using fake names. Klein admitted that he prescribed Jackson Demerol and Xanax, but denies doing anything illegal.

Klein has reportedly not provided certain medical records the coroner's office is seeking as they attempt to determine Jackson's cause of death.
