Authorities say Michael Brandon Hill, 20, faces numerous charges in relation to a school invasion on Tuesday. Two people who encountered Hill, accused of opening fire inside a U.S. school, say he told them was off his medication, though a motive remains unknown. Antoinette Tuff, the bookkeeper at Ronald E. McNair Discovery Learning Academy, told ABC on Wednesday the suspect told her he hadn't taken his medication.
