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

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 was executed for the killings in 2017 of nine victims, most of whom had posted suicidal thoughts on social media.
