A judge in Fort Worth has sentenced a teenager to 40 years’ behind bars for his part in a November crime spree that included severely beating an 85-year-old deaf man. The teen also robbed clerks at gunpoint at two convenience stores. The judge denied prosecutors’ request that the teen be tried as an adult. In just three years, the juvenile court can parole him from the juvenile facility at which he will serve his time. Two other teens charged in the crime spree will be tried as adults.
