Police said Urbanski, who is white, stabbed Collins in a “totally unprovoked” attack while Collins was visiting friends at the university in College Park. Collins, a Bowie State University student, was waiting with two friends at a bus stop when Urbanski approached and told Collins, “Step left, step left if you know what’s best for you,” according to police charging documents. Collins wouldn’t move, and Urbanski pulled a knife and stabbed Collins, police said.
