A father has been charged with murder on Friday after allegedly shooting a drunk driver moments after he plowed into his truck killing his two young sons. David Barajas, 31, and his sons, 12-year-old David Jr. and 11-year-old Caleb, were about 50 yards from their Houston-area home when a car crashed into them on a dark rural road. David Jr. died at the scene, while Caleb died later at a hospital.
