31-year-old Clarkson graduate student Ma Tian, was killed by a village police officer after he was found stabbing a classmate in his apartment. When officers Matthew A. Seymour and Clinton Perrigo arrived at 401 Swan St. in the Swan Landing Apartments at 2:45 p.m. Thursday, September 10, 2015, they found 31-year-old Ma Tian on top of 25-year-old Jiang Yazhen, stabbing her and himself. Village Police Chief Kevin M. Bates said Ma refused to obey the officers’ commands to drop the knife. “They had their weapons drawn and asked the assailant several times to drop the knife and he did not comply,” Mr. Bates said. “Officer Seymour shot four times, killing Ma on the spot.”

Authorities say a man fatally shot by police and the woman he stabbed to death inside an off-campus apartment were both graduate students from China. State police on Friday identified the attacker as 31-year-old Tian Ma and the victim as 24-year-old Yazhen Jiang. They say both were pursuing doctorates at Clarkson University. Their hometowns were not initially available.
