With credit for good behavior, it was anticipated that Hilton would only serve 23 days of her 45-day sentence; however, in an unexpected turn of events, Los Angeles County Sheriff Lee Baca signed orders, reassigning Hilton to 40 days of home confinement with an electronic monitoring device due to an unspecified medical condition.
