Aichi prefectural police said Sunday that a suspect in the murder of a woman and her son in the town of Kanie last week remained in the house for more than 10 hours after the murders and that he left, apparently wearing a pair of sneakers belonging to one of the residents.
Police found the body of Masaki Yamada, 26, in a bedroom on Saturday, stabbed in the back and neck, after an officer visited the home around 12:30 p.m. following a call from a colleague concerned that Masaki had not turned up for work. When the officer arrived, he rang the doorbell and then saw Masaki's younger brother Isao, 25, trying to get out of a window. Isao, whose legs were bound and who had knife wounds to his neck, told the officer that the assailant was still inside.
Police said the officer peered through the partially open front door and saw a man dressed in black crouching inside. He ordered the man to come out, but upon receiving no response, he retreated to call for backup on his radio. By the time other officers arrived, the suspect had vanished. A pair of sneakers belonging to Isao were also gone. Police believe the suspect switched shoes and carried his away with him.
On the following day, police found the body of the men's mother, 57-year-old Kihoko Yamada, under a blanket in her closet.
Isao told police that he came home about 2 a.m. on Saturday and that as soon as he entered the house, he was attacked by a man, speaking Japanese in a strange accent. He said the man put a towel over his head. He told police he doesn't know what the man was doing in the house from 2 a.m. until the time the police officer arrived at 12:30.
Police said Sunday that three different weapons were used in the attacks. The mother died of head injuries caused by repeated blows with a blunt instrument, believed to be a wrench found near the bathroom sink on the first floor. Masaki was apparently killed by a cooking knife. A smaller knife found is believed to be the weapon used on Isao. The family cat was also killed. The two knives had been washed and were inside a plastic bag, police said.
Police have come under fire for allowing the suspect to escape. A police spokesman said Saturday that the officer on the scene who called for backup was only gone for about three minutes and that the suspect must have left through the back door during that time.© News reports
