(AP) — A former Beatrice State Developmental Center worker charged with abusing developmentally disabled adults has reached a plea deal.

The state and attorneys for Matthew Pangborn reached an agreement Friday. Details of the deal have not been released.

Pangborn was convicted in July 2012 of four counts of abusing a vulnerable adult and several other charges. He was sentenced to 15 to 23 years in prison.

The Nebraska Supreme Court later ordered a new trial after it determined a chart of Pangborn’s alleged abuses should not have been presented to jurors.

Pangborn will be in Gage County District Court Tuesday for re-arraignment.

Sixteen center employees were fired or suspended following an investigation into the alleged abuses. Five were charged, but most entered pleas to reduced charges.
