Villanova University’s campus was briefly under a lockdown Sunday evening as police searched for the stabbing suspect.

NBC10 reported that Marquez was driving a U-Haul as part of a caravan of vehicles when a dispute arose. Marquez allegedly struck the victim’s vehicle, then got out and started hitting the victim. Marquez then got a knife from his U-Haul and stabbed the victim in the back, NBC10 reported.
Pennsylvania State Police recovered a knife that was being tested as part of the investigation, NBC10 reported.
