Morris also struck another corrections officer in the face and can be seen running around while other prisoners reportedly shouted "Hope she dies".Christensen had to go to an intensive care unit for her injuries, and Morris is charged with two counts of battery by a prisoner and one charge of aggravated battery. The video was released to a civilian review panel which was looking for ways to improve the jail's conditions.News Link: www.wsaw.com/home/headlines/Surviellence-Vid-of-Marathon-Co- Notes: Two different angles are included, no audio on either video.
