NAZ Today Reporter Makayla Clark shares insight to the double life sentencing of Derek Barnett, as he will be behind bars for the rest of his life. However, despite conviction, Barnett says he is innocent.

One theory behind the crime is that Barnett may have been burglarizing the DeMaria's home and as they were arriving back home, Barnett had shot and killed them. Barnett was later found in Colorado and then extradited back to Arizona. Barnett was also found guilty using weapons while on probation as well as stealing the couple's gun and vehicle.
