FRISCO, Texas -- A Frisco man was sentenced to life in prison Monday for murdering his mother and father.
On August 11, 2014 Frisco police officers responded to a 911 call of shots fired at a home near Coit and Shepards Hill.
When the officers arrived they found Ryan and Maria Callens deceased in their bedroom along with a rifle on the floor, outside the master bedroom.
The rifle had a flashlight attached to it with duct tape.
The victims' then-16-year-old son, Zachary Callens was outside the home near his sister when police officers arrived.
Frisco Officer Hinton Butler overheard Callens explain to his sister that "he did it." When she asked him if the murders were his plan, he said it was.
Multiple items of evidence were collected from the scene including the rifle with the flashlight, duct tape and bullets found in Callens' room.
DNA evidence linked Callens to the flashlight and the duct tape on the rifle.
Frisco Detective, Daniel Bardwell and Sgt. Nelson Walter charged the juvenile with the murder of his parents and was later certified to stand trial as an adult.
The jury found Callens guilty of both murders and assessed a punishment of life in prison for each.
