Sacramento mom says "hero" son shot, killed Oregon school shooter

A Sacramento mother says her son acted on instinct when he confronted and fatally shot a gunman during a deadly school shooting in Oregon , an attack that killed three children and a teacher.

Police said Friday they believed the teenage gunman was targeting a class of children with special needs when he opened fire at the school.

36-year-old Kaylub Giamanco was identified as the armed bystander who pursued the shooter into Silver Rail Elementary School in the city of Bend on Thursday. Giamanco is a father of two children who attend the school.
