The U.S. Marshals Service investigated the case.

During the investigation of the 2012 crime, law enforcement learned Donnie Neice was wanted in Las Vegas for attempted homicide.

Barnes is described as being white, 5' 3" with brown hair and brown eyes.

He climbed a wall, climbed a chain link fence and entered a light-colored Sport Utility Vehicle.

According to the Wyoming Division of Criminal Investigation, he was registered as a sex offender in 2014.

Cell phone providers can track a phone's location through cell phone towers, Global Positioning System coordinates, and other means.

If you see him, please contact the Natrona County Sheriff's Office.

But he and an accomplice were arrested a year before in Converse County.
