McKINNEY, Texas (AP) — An 18-year-old North Texas man must serve life in prison for the 2014 killing of his parents in what prosecutors call a dispute over unfinished schoolwork and disobedience.
Zachary Callens was sentenced Monday in McKinney.
A Collin County jury on Friday convicted Callens of murder in the deaths of his parents — Ryan and Maria Callens. The victims were shot to death in the family's home in Frisco, about 30 miles north of Dallas.
The home-schooled son was 16 years old at the time of the August 2014 slayings, but he was tried as an adult. A judge who certified Callens as an adult cited the brutality of the crime and the teen's lack of remorse after the deaths.
