Kanagawa Prefectural Police received an emergency call in the early hours of April 20, and officers arriving at an apartment in Naka Ward, Yokohama, found a dead woman bleeding from her body and covered with a jacket. Noting that there are a number of slash and stab wounds on her body, investigators said they suspect that she had been murdered.
Local police believe the woman is a 19-year-old Russian national from her alien registration certificate, and are trying to confirm her identity.
A 36-year-old Japanese man, who claims to be an acquaintance of the victim, said he visited the room with a foreign man and then alerted prefectural police after seeing her slash her own hand.
However, as his statements contradict the actual conditions of the victim's body, investigators are cautiously investigating the case.
A 37-year-old woman who lives downstairs in the same apartment complex said she heard a man and a woman scream.
"I heard a man talk loudly and a woman cry. I also heard the huge sound of something falling to the floor," she said.
