ROCHESTER, N.Y. — A college student from New York City has pleaded not guilty to fatally stabbing a University of Rochester classmate at a fraternity party.

Dozens of students and relatives were in court Monday for the arraignment of 20-year-old Daren Venable on a murder charge.

Police said Jeffrey Bordeaux Jr., a 20-year-old junior from suburban Rochester, was stabbed at the Delta Upsilon fraternity house early Saturday. They said the men got into an argument that stemmed from a long-running dispute.

Neither belonged to Delta Upsilon. Venable, who’s from Brooklyn, is a member of another campus fraternity. Bordeaux was a scholarship-winning political science major who was on the school’s track team and was to begin studying in Shanghai next month.
