DA David O'Leary expects that plea and resignation to come April 7. He won't say to which felony Gilbertson was expected to plead.
Court documents say the coroner has admitted taking pain medication from the scenes of death investigations, telling investigators she couldn't afford the co-payments for her prescriptions.
Court records say she's also admitted giving pain medication to a worker in the Rock County Public Works Department, which is located in the same building as the coroner's office.
She remains coroner, but is on personal leave.
