Japan has executed a man dubbed the “Twitter killer,” who was convicted of murdering and dismembering nine people, mostly women, in the country’s first use of capital punishment in nearly three years.

Takahiro Shiraishi, 34, was hanged after murdering nine people — eight of whom were young women he targeted after they expressed suicidal thoughts on Twitter.

Takahiro Shiraishi, known as the “Twitter killer,” was sentenced to death in 2020 for the killings in 2017 of the nine victims, most of whom had posted suicidal thoughts on social media. He was also convicted of sexually abusing female victims.
