1-Page Summary

Lured Victims on Twitter

Takahiro Shiraishi, using the Twitter usernames Suspension Pro and Shinatai, preyed on individuals with mental health issues, promising to assist with their suicidal thoughts. His victims, ranging in age from 15 to 26, were lured through five Twitter accounts, with Takahiro masquerading as a sympathetic figure who could relate to their distress. He took advantage of their vulnerabilities, manipulating emotions and discussing personal challenges such as academic pressure, social anxieties, postpartum depression, and self-esteem issues. His connection with these victims was a calculated ruse to eventually meet and manipulate them in person, offering a companion to “leave together,” a euphemism for suicide.

Committed Atrocities

Takahiro Shiraishi committed dismemberment of his victims, storing their body parts including severed heads in his Tokyo apartment. He developed a systematic process for managing and disguising the smell of decay with bleach and cat litter, while also keeping various tools for the dismemberment. His apartment was discovered as a grotesque storage with human remains in containers and body parts disposed of as household trash. Takahiro displayed no remorse for his actions, expressing detachment from the severity of his crimes and forgetting the victims' names, recalling only their Twitter handles. He demonstrated pride in his manipulative abilities and blamed Twitter and the Japanese government for his access to victims, instead of acknowledging his malicious intent.

Sentenced to Death

Takahiro Shiraishi was sentenced to death after facing nine charges of murder among his 18 serious charges. The charges encompassed robbery, forced assault, mutilation of corpses, and their abandonment. His sentencing took an exhaustive one and a half hours to proclaim. During investigations, evidence such as his internet search history pointed to his awareness of the crime’s seriousness. While specifics regarding his capture are not detailed, it is known that a friend assisted the police, leading to his trial and eventual death sentence.

Lured Victims on Twitter

An individual with the Twitter username Suspension Pro, who was also linked to the account Shinatai, preyed on vulnerable individuals, leading to multiple missing persons cases.

Preyed on Vulnerable Individuals

Victims experienced mental health issues

Takahiro, the person behind Suspension Pro, utilized five different Twitter accounts to target potential victims by focusing on negative thoughts and emotions. He lured them with the offer of helping with "leaving," a veiled reference to supporting their suicidal ideations. Individual cases include Yumi, who felt he could relate to her desire to "leave," and Ivy, whose last post indicated a fear of leaving alone.

Ages ranged from 15-26

Takahiro targeted individuals ranging in age from 15 to 26, believing that the police wouldn't actively search for them due to their age. Victims included teenagers and young adults in various states of vulnerability:

  • Bella, a 15-year-old high school student, was under academic pressure and was invited by Takahiro to escape this pressure by staying at his apartment.
  • Ella, a 26-year-old mother dealing with postpartum depression and caring for a daughter with a developmental disability, was lured in her search for someone who could relate to her struggles.

Committed Atrocities

Stephanie Soo describes harrowing details of committed atrocities involving the dismemberment of bodies and the stark absence of remorse by the perpetrator, Takahiro.

Dismembered Bodies

Stored Body Parts in His Apartment

Takahiro engaged in the gruesome process of dismembering victims, meticulously removing body parts and attempting to manage the overwhelming smell by using bleach, cat litter, and a commercial-grade sterilizer. Over time, he refined this process, storing the remained body parts including severed heads in his apartment. His preparation included purchasing tools like a single-sided saw, kitchen knives, a sharpener, scissors, and setting his apartment with rope and saws to facilitate this horrific ritual.

The Tokyo apartment became a chilling storage space for the results of his actions, holding things such as discolored human heads, some with cloudy eyeballs, in boxes filled with cat litter to cover the odor. Severed heads and human bones were found among 240 bones and blood-stained items. He described the difficulty of dismembering a person's neck and upper face, despite storing boxes of bones in his living space. Other disposed body parts were wrapped in pet pee pads, placed in Ziplock bags, wrapped in newspaper, and discarded in the apartment building's trash.

Showed No Remorse

Blamed Twitter, Lawyers, Probation

Takahiro exhibited a chilling detachment and lack of remorse over his actions, not feeling regret for most of his victims and forgetting their names in favor of their Twitter handles. His slight regret stemmed only from how the events led to his arrest, not from the acts themselves. He even felt pride in being able to overpower his victims, particularly his only male victim, Charlie.
