Nevada Highway Patrol Office spokesman Jeremie Elliott says he doesn't know Reid's condition after the crash, which happened about 1:10 p.m. Friday on Interstate 15.
The freeway runs parallel to the Las Vegas Strip.
Elliott says six vehicles were involved in the apparent chain-reaction crash, including two Las Vegas police vehicles, two civilian vehicle and two Capitol Police vehicles.
Elliott says four tow trucks were summoned. It's not clear whether anyone else was injured.
