EP182: Twitter Killer: Japanese Serial Killer Takahiro Shiraishi
from Psychopedia · host Investigator Slater
TRIGGER WARNING: This episode contains discussions of suicide and may be distressing to hear. Please listen with caution.In 2017, a series of disappearances began to ripple through Zama, just outside Tokyo. The victims were young women between the ages of 17 and 26 who all left behind the same digital footprint: Twitter posts expressing a desire to die. What no one realized at the time was that those posts had drawn the attention of a murderous predator. By the end of that year, the investigation led police to a single apartment, where a scene of calculated horror was waiting: nine dismembered bodies with severed heads and mutilated limbs found scattered and hidden in boxes. At the center of it all was Takahiro Shiraishi, later known as “The Twitter Killer,” a man who turned vulnerability into a hunting ground and despair into a lethal weapon.
