A female 19-year-old student who admitted killing an elderly woman and poisoning a male high school classmate appeared to show no discomfort over what she did, allowing the woman's body to remain in her apartment for weeks as it decomposed.
The Aichi Prefectural Police said Monday the Nagoya University student appeared to have made no effort to cover up the killing of the 77-year-old woman, a member of a religious group whom she had befriended.
The day after the slaying, she took an overnight bus from Nagoya to Miyagi Prefecture to stay with her parents, the police said.
