Police say a 16-year-old boy is being held on a capital murder charge after being arrested Wednesday at a high school in suburban Richardson. He is the third teen accused of killing 66-year-old Lorenzo Moreno early Sunday.
Authorities say a group of teenagers went to Moreno's house because one of the teens had a feud with Moreno's granddaughter. An argument quickly escalated. Moreno was shot, and his granddaughter, wife and son were beaten. A television was also stolen.
The 16-year-old girl believed to be feuding with Moreno's granddaughter is in custody, as is her 17-year-old boyfriend.
