A black ROTC cadet set to graduate from Bowie State University this week was stabbed to death by a white University of Maryland student who’s a member of a racist online hate group, the Baltimore Sun reports.

Richard Collins III, 23, was visiting UMD this graduation weekend when he was attacked by Christoper Sean Urbanski, 22. Collins and two friends were awaiting an Uber ride around 3 a.m. Saturday morning when an “intoxicated and incoherent” Urbanski stabbed him. Authorities who reviewed videotape of the incident described the attack as unprovoked.

Police charged Urbanski, a member of the Facebook group, “Alt-Reich Nation,” with first-degree murder Sunday. The FBI is investigating the stabbing as a possible hate crime.
