Dan Haggerty

==Background==
Dan is the father of Dale Haggerty who attended ALPA.
Dan arrived on campus in the early evening. He was operating on fear and adrenaline, and was very confrontational. When he found out his son was still in Mrs. Goodell's class, he set off to teach her. He barged past Adrian to enter the classroom to find his son dead in the closet. When his son attacked, he squeezed the trigger on his gun and shot Mrs. Goodell and several of the other children in the classroom.
