OMAHA, Neb. (AP) – A prosecutor has filed charges against five staffers accused of abusing developmentally disabled residents of the Beatrice State Development Center. Gage County Attorney Roger Harris announced Monday that he has filed charges ranging from abuse of a vulnerable adult to theft and strangulation against the five staffers, identified as Cameron Barnes, Matthew Johnson, Carmen Yates, Cody Creek and Matthew Pangborn. All of the charges are felonies. The charges come more than a month after a center staffer called Nebraska Adult Protective Services to report the abuse. A subsequent investigation by the Nebraska State Patrol and the center says those staffers charged often hit, slapped and choked developmentally disabled residents.
