Police have uncovered new evidence in the case of the death of 9-year-old Tsukudanishi Elementary School student Seika Yamamoto. According to information gathered by authorities, Seika's twin sister, with whom she had lived with until January of this year, was beaten in the head by their mother Mina, 34, and suspect Yasuhiro Kobayashi, 38, both of whom have been arrested on suspicion of abandoning a corpse.
Investigators have revealed that both Seika, her sister and mother moved in together with Kobayashi at the end of last year. The twin sister lived in the residence until Kobayashi got angry with the girl and forced her to return to her father's house elsewhere in Nishi-Yodokawa Ward. When asked by police and school authorities about the short period she lived with Kobayashi, the girl testified that, "When we did something wrong, my mother would beat us in the head with her fist. Sometimes she wouldn't give us any food for a day."© News reports
