Hero cop who stopped knife-wielding suspect at Ohio State University

Ohio State University's public safety director praised the quick and responsible actions of the police officer who killed the suspect in Monday's attack on campus. "We all owe [him] a debt of gratitude," Monica Moll said of OSU Police Officer Alan Horujko.

Horujko, 28, is a nearly two-year veteran of the campus police department, and Moll said he took action immediately after seeing Abdul Razak Ali Artan allegedly drive a vehicle into a number of pedestrians.
