A junior high school teacher was sent to prosecutors on Thursday after he was arrested a day before on suspicion of killing a man during a break-in at a home in Tokyo in February.
Kosuke Omoto, 36, allegedly fatally stabbed Masafumi Yamagishi, 63, at the latter's home in Tokyo's Edogawa Ward, apparently to steal valuables. Omoto is believed to have accumulated millions of yen in debt through gambling and foreign exchange trading, investigative sources said.
Omoto, who lives in nearby Koto Ward, told the police that he had "no connection" to the incident when he was arrested, but has since kept silent, according to the sources. The killing took place on Feb. 24, just 150 meters away from the public junior high school where Omoto works.
According to the school, the suspect worked the first half of the day of the incident but took time off in the afternoon.
Omoto apparently killed Yamagishi after the latter discovered him in his home when he returned from work.
Yamagishi was found collapsed at the entrance with more than 10 slash and stab wounds, including to his face, neck and arms, while bloodstains were also found in the living room.
Police believe Omoto spent a total of 10 minutes inside the property.
