Using the Reid technique - a three-part process that includes Fact Analysis, Behavior Analysis Interview and the Reid Nine Steps of Interrogation - Byington was able to get Christopher to open up about the night his parents were murdered.

Byington started the interrogation by telling Christopher he had interviewed various people about the case and deduced "there's no doubt you caused the death of your parents." In shock, Christopher ultimately broke down and admitted the murders were "just an accident." He told detectives that he went to Pizza Plus around 10:30 PM on the 29th and got into an argument with his parents about money.

Christopher detailed how he slit his mother's throat before chasing his father out of the restaurant, grabbing him from behind and choking him. He then went back inside and bludgeoned his mother with the fire extinguisher to make sure she "was not moving." Christopher said he replaced the fire extinguisher and cut his father's throat before leaving the crime scene.

Christopher was charged the capital murders and robberies of Harvey and Valerie Looney, and he pleaded no contest "..he was sentenced to life in prison".
