(TOKYO) — Two apparent explosions hit the Japanese city of Utsunomiya back-to-back Sunday, killing one person and injuring three others in what police are viewing as a possible suicide. Japanese media reports suggest that the victim, believed to be a 72-year-old former military officer, may have set his house on fire, blown up his car in a public parking lot and then blown himself up in a nearby park. A note found in the clothing of the badly burned victim included the name of the former officer, Japanese broadcaster NHK and other media reported.
