Counterterrorism agents secure an area to handle Jutas Csanad Horvath, whom police have identified as the killer of four members of his own family, in the town of Kulcs, 60 km (37 miles) south of Budapest, April 6, 2012. Horvath, 23, also seriously wounded three others in Kulcs on Friday before he was detained, a spokesman for the national police said. Police began to question Horvath a few hours after the attack, after capturing him in a marsh not far from the murder scene. REUTERS/Bernadett Szabo (HUNGARY - Tags: CRIME LAW)
