(AP) — A former Beatrice State Developmental Center worker convicted of abusing developmentally disabled adults has again been sentenced to prison.

On Wednesday Matthew Pangborn was given nine years and four months to 15 years in prison. He will be serving consecutive sentences on three counts of abusing a vulnerable adult and two counts of strangulation. Four additional charges were dropped as part of a plea agreement that included Pangborn’s pleading no contest to all five counts.

In July 2012 Pangborn was found guilty 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 determined that Pangborn should be retried because a chart prosecutors made shouldn’t have been given to the first jury during deliberations.
