Japan executes ‘Twitter killer’ behind 2017 serial murders

Japan has carried out its first execution in three years, putting to death Takahiro Shiraishi, the man behind a string of gruesome murders in 2017.

Known as the “Twitter killer,” Shiraishi lured nine people, mostly young women between the ages of 15 and 26, by connecting with them on Twitter, where he posed as someone who could support those contemplating suicide. His profile read, "I want to help people who are really in pain. Please DM me anytime."

Once in contact, Shiraishi manipulated his victims, often suggesting he could help them end their lives, and in some cases, falsely claimed he would die alongside them. Instead, he strangled and dismembered them in his apartment in Zama, near Tokyo.

The horrifying crimes came to light in October 2017 when police, investigating the disappearance of one of the victims, discovered body parts stored in coolers and toolboxes. The apartment was soon labeled a “house of horrors” by local media.

During trial proceedings, prosecutors pursued the death penalty, arguing that Shiraishi preyed on vulnerable individuals. His defense team, however, attempted to reduce the charges, claiming it was “murder with consent” and suggesting his mental state needed evaluation.

Shiraishi eventually rejected his lawyers’ version of events, admitting to the killings and insisting his victims had not consented.

In December 2020, he was sentenced to death, drawing significant public attention. Hundreds gathered at the Tokyo court for the verdict.

Following the case, Twitter, now known as X, updated its policies to prohibit users from promoting or encouraging suicide or self-harm.

The Ministry of Justice confirmed Shiraishi’s execution on Thursday, marking the first instance of capital punishment in Japan since 2022.
