Two more former employees at a Nebraska center for developmentally disabled adults will serve time behind bars for abusing residents.

Cody Creek, of Beatrice, was sentenced on Wednesday to eight months in the Gage County jail for attempted abuse of a vulnerable adult. Carmen Yates, also of Beatrice, was sentenced to six months in jail on the same charge.

They were among five workers fired and charged after an investigation at the Beatrice State Development Center in 2011. The investigation found at least seven residents were routinely abused.

In August, Cameron Barnes and Matthew Johnson were sentenced to up to eight years in prison on two counts of abuse of a vulnerable adult.

Matthew Pangborn, who was convicted of nine abuse charges, will be sentenced Oct. 3.
