A man in custody following the discovery of parts of nine corpses in his apartment in Zama City has told police that he disposed of portions of the bodies in the trash, reports the Sankei Shimbun (Oct. 31).
Authorities found the human remains in Shiraishi's home while investigating the disappearance of a 20 year old woman from Tokyo, whose body was then found among the remains.
According to reports, police found parts of a dismembered body in a picnic cooler covered with cat litter inside the man's apartment.
An investigation was launched after the woman's older brother reported her missing to the Takao Police Station in western Tokyo on October 24, saying he had not been able to contact her since October 21.
According to Jiji Press (wire service in japan), police found the two heads inside a cool box at the entrance of the apartment before being shocked about the rest of the bodies.
After his arrest, Shiraishi is said to have admitted dismembering the victims in his bathroom, and putting some of the body parts in rubbish bins.More news: Ever regretted sending a WhatsApp message? Now you can delete it

Police have said Shiraishi confessed he tried to hide evidence. Investigators plan to carry out DNA tests in an effort to identify the deceased, they said.
The woman had met Shiraishi after posting on a suicide website that she wanted to kill herself.
The gruesome case captured widespread attention in a country known for public safety, topping news with reports that showed the building where the suspect lived in a small studio apartment.
"I thought it smelled like sewage", one neighbor said.
Shiraishi's case, involving social media suicide pacts, connections to Tokyo's notorious red-light district and neighbours who did not report a noxious smell coming from the suspect's apartment for months, has the hallmarks of a grotesque thriller novel or horror movie. He added: "It was something I never smelled before".
Earlier in October, a 32-year-old father was arrested on suspicion of stabbing his daughter to death.
