Officer Peterson is one of the older police officers in the Park County Police and has shown to be one of the more capable officers and has been willing to question Harrison Yates even when he's wrong. He was chosen to go undercover at the Monster Mash, but efforts to destroy Gangnamestein resulted in him nearly being shot to death, something the department covered up. He's recovered though -- and back on the force.
