He was armed with four weapons — three handguns and one assault weapon, according to NBC News’ Pete Williams. He was not a student at the school, authorities said. They are still working to figure out his connection to UCC, Williams said, and have uncovered “documents that expressed the philosophy of hate.” h/t huffington post

Mercer’s social media account featured photos of the Irish Republican Army, a revolutionary group that has historically been rooted in acts of violence.
