22 year-old Robert "Caleb" Engle returned to his church on Sunday. Just a week earlier, a gunman opened fire on parishioners at Burnette Chapel Church of Christ in Tennessee. Engle is credited with stopping the attacker, who police identified as 25-year-old Emanuel Samson, after he allegedly shot several people inside the church as well as 39-year-old Melanie Smith, who died in the parking lot.
