A Casper man has changed his plea in a case where he was involved in a crime spree.

Nineteen-year old Brenton Livermoore has pleaded guilty to three counts of aggravated robbery, along with four counts of burglary and one count of conspiracy.

According to prosecutors, in September of last year, Livermoore along with his friend Donald Hensley, robbed three people at gunpoint and burglarized an auto body shop.

Investigators later determined that Livermoore was also involved in a number of residential and business burglaries prior to the aggravated robbery case.

As part of a plea bargain, the state will seek no more than a six-to-eight year prison sentence at the Wyoming State Penitentiary.

Livermoore will officially be sentenced at a later date.
