Japan’s ‘Twitter killer,’ who murdered 9 people, is sentenced to death

A Japanese court Tuesday sentenced a man to death for killing and dismembering nine people, most of whom had posted suicidal thoughts on social media, in a case that shocked the country.

The Tachikawa branch of the Tokyo District Court found Takahiro Shiraishi, known as the “Twitter killer,” guilty of killing, dismembering and storing the bodies of the victims in his apartment in Zama, near Tokyo.

Shiraishi, 30, pleaded guilty and said he would not appeal his death sentence.

Police arrested him in 2017 after finding the bodies of eight women and one man in cold-storage cases in his apartment.

Investigators said Shiraishi approached the victims via Twitter, offering to assist them with their suicidal wishes. He killed the women, including teenagers, after raping them, and also killed the boyfriend of one of the women to silence him, investigators said.

On Twitter, Shiraishi used the name “Hangman,” promising to help his victims die and inviting them to his apartment.

As Japan’s serial killing case unfolds, people ask: Did killer find victims through Twitter?

After Aiko Tamura, a 23-year-old Tokyo resident, posted on Twitter her desire to commit suicide, her brother frantically began looking for clues to her whereabouts after she went missing Oct. 21.

Although his lawyers argued that he assisted the victims in their own suicidal wishes, Shiraishi later said he killed them without their consent.

In the ruling, presiding Judge Naokuni Yano said none of the victims agreed to be killed and that Shiraishi was fully responsible for their deaths, according to media reports.

Yano said the crime was extremely heinous and had caused fear and concern in a society where social media have become an indispensable part of everyday life, NHK public television reported.

Japan’s suicide rate ranks among the world’s highest. Following a recent decline, the number has climbed back up this year as people were hit by the effects of the pandemic.

Japan’s crime rate is relatively low, but there have been some recent high-profile killings and crimes. Last year, an arson attack on an anime studio in Kyoto killed 36 people.
