"As Japan’s serial killing case unfolds, people ask: Did killer find victims through Twitter?"
Japanese media outlets, citing police sources, say Shiraishi approached most victims using Twitter. Shiraishi, who authorities say referred to himself as a suicide expert on hanging, told his victims he would help them with their suicides, even die with them, reports said.
One Twitter account linked to him, @hangingpro, carried the message: “I would like to help those who are truly suffering. Feel free to DM me.”
According to media reports, Shiraishi used to work in the red light district of Tokyo as a scout, someone charged with finding women to work as prostitutes.
