New details are emerging in Wednesday's triple stabbing incident at Carrick High School. According to a criminal complaint, video shows 16 year old Anthony Taulton fighting another student as a teacher tries to intervene. Taulton told police he'd received threats in a group Instagram chat weeks earlier and warned his mother he feared going to school. The morning of the incident, he reportedly took a kitchen knife from home. School officials say Taulton arrived late on Wednesday, entering through the school’s cafeteria entrance and passing through a metal detector. Authorities say he later confronted students from the chat in a hallway, where an argument escalated where he allegedly stabbed three of them. Taulton is charged with three counts of felony aggravated assault and misdemeanor counts of possession of weapons on school property and possession of instruments of a crime in connection with the incident.
