SAITAMA – Police, who are interrogating a 20-year-old college student from Saitama Prefecture on suspicion of stabbing to death a 21-year-old woman in the city of Iruma, in the same prefecture, revealed Friday that the suspect said that he “just wanted to kill anyone.”
Yusuke Numata, 20, from the city of Saitama, was arrested on murder charges Thursday after he turned himself in to the police earlier in the day and confessed to having killed a woman in Iruma.
“I bought the knife just before (the assault),” he was quoted by an investigator as saying.
“I was thinking about killing someone so I had a knife with myself, and I bumped into her when she left a convenience store,” he reportedly told the police, adding he attacked the woman from behind.
The victim was identified as Shizuka Sato, 21, also from Iruma. She was stabbed between 10:15 and 10:45 p.m. on Wednesday near her home.
She was a third-year student at a private university in Tokyo. Police said the suspect and the victim, however, did not attend the same college and were not in any relationship.
The police said there were no cut wounds on Sato’s arms or hands, indicating that the woman had no time to resist.
Sato’s body was found with about a dozen stab wounds in her back, chest and abdomen.
The police added that soon afterward, Numata returned home to change his clothes and spent about three hours. He then left home and headed to Sayama Police Station, where he turned himself in in the early hours of Thursday.
According to Saitama Prefecture Police reports and investigative officers, on the day Sato was murdered, she was on her way home after having finished her shift at a convenience store located in her neighborhood, where she worked part time.
The police said Numata knew that Sato worked at the convenience store and quoted him as saying: “I noticed (the victim) was the convenience store clerk after stabbing her.”
