Authorities made the disturbing discovery in October 2017 while investigating the disappearance of a 23-year-old woman last seen walking with Shiraishi.
Cops found the victims' body parts in Shiraishi's flat in the Japanese city of Zama, near Tokyo.
One resident told The Japan Times in 2017: 'I thought it smelled like sewage. It was something I never smelled before.'
Another neighbour said they noticed a 'nasty smell' coming from the flat.

He told prosecutors he met the youngsters on the social media platform Twitter, now known as X.
He told them he could help them die, even claiming in some cases he would kill himself alongside them.
His Twitter profile wrote: "I want to help people who are really in pain. Please DM [direct message] me anytime."
Prosecutors demanded the death penalty for Shiraishi, while his lawyers argued for a prison sentence, claiming his suicidal victims had consented to their deaths and that he should be charged with "murder with consent".

They also called for his mental state to be assessed.
But Shiraishi later disputed his own defence team's version of events, revealing he killed without the victims' consent.
435 people showed up to watch the 2020 verdict sentencing him to death - despite the court having only 16 public seats - Japan's public broadcaster NHK reported.
The murders also prompted Twitter to change its rules to state users should not "promote or encourage suicide or self-harm".

What is Japan's death penalty?
JAPAN'S justice system allows the death penalty for serious crimes like murder, typically carried out by hanging.
The nation's death penalty dates back to the Meiji era - with the current legal framework established under the Penal Code of 1907.
Executions are rare and usually follow a lengthy appeals process.
The justice minister must sign the execution order.
Inmates are often told just hours before, and the executions are carried out in total secrecy.
Between January 2000 and June 2025, 99 inmates have been executed in Japan.
