TOKYO (TR) – It was 10 years ago on Monday that a 45-year-old professor at the Korakuen Campus of Chuo University was fatally stabbed in a bathroom, reports Fuji News Network in a flashback.
At around 10:30 a.m. on January 14, 2009, a student found Hajime Takakubo, a professor in the Faculty of Science and Engineering, collapsed and bleeding with dozens of stab wounds to his chest and back in the restroom, located on the fourth floor of a school building.
Takakubo was confirmed dead about one hour later at a hospital. An examination of his body revealed that he had been stabbed more than 60 times. The cause of death was loss of blood, police said at the time.
Several people witnessed a man in his 30s, wearing a black coat and black cap, leave the toilet just before the victim was found, police said. and the man ran from there
That May, police arrested Ryuta Yamamoto, a then 28-year-old part-time worker from Hiratsuka City, Kanagawa Prefecture, on suspicion of murder.
A DNA analysis of material found under the fingernails of Takakubo proved to be a match for Yamamoto. Upon his arrest, he declined to give a motive for the crime.
In December, 2010, the Tokyo District Court acknowledged that Yamaoto suffered from a delusional disorder in handing him an 18-year prison term.
