WASHINGTON, Pa. —(WPXI)- A Washington & Jefferson College student is facing criminal charges after a threat was made against the campus on an anonymous social media app. A threatening post was made against the school on the app YikYak in February. It said, “No cap, how many people you think I can kill if I shoot the joint up” and then was followed by a response saying, “I’m thinking like 30-50.” Attendance to in-person classes was made optional as a result. Police got a search warrant and got user information from YikYak. They say the person who made the original post and response was Trevor Jon McDonald, 23. McDonald was suspended from Washington & Jefferson College before the post was made for an unrelated incident. Members of the FBI met him at his house in Chalfont and showed him a picture of the post. Police said he admitted to making it. McDonald faces a felony charge of terroristic threats causing the evacuation of a building and criminal use of a communication facility.
