The Crime
The Setagaya Family Murders took place in the early morning hours of December 30, 2000, at the Miyazawa family home in Setagaya-ku, Tokyo. The victims were:
- Mikio Miyazawa (44): The father of the family, a successful businessman and avid golfer. He was found dead in his living room, having been stabbed multiple times.
- Yasuko Miyazawa (41): Mikio’s wife, a homemaker known for her warm and caring nature. She was found dead in her bedroom, also with multiple stab wounds.
- Niina Miyazawa (11): The couple’s daughter, a bright and popular student. She was found dead in her bedroom, with stab wounds and signs of a struggle.
- Rei Miyazawa (8): The couple’s son, a playful and energetic child. He was found dead in his bedroom, with stab wounds and signs of a struggle.
The crime scene was meticulously staged, with no signs of forced entry and no apparent motive for the murders. The perpetrator had carefully cleaned the house, removing any obvious traces of their presence, and even left behind a message written in English on the wall, “I’m sorry.”
The evidence gathered at the scene included:
- Fingerprints: The perpetrator’s fingerprints were found on various items throughout the house, suggesting they had spent a significant amount of time there.
- DNA: DNA evidence was also found, indicating that the perpetrator was likely male.
- Missing Items: Several items were missing from the house, including a credit card, a mobile phone, and a watch.
- Strange Messages: In addition to the message on the wall, there were other unusual messages written in English on various surfaces.
These pieces of evidence, along with the lack of a clear motive, have led to various theories about the identity and intentions of the perpetrator.
Theories
Theories surrounding the Setagaya Family Murders range from the mundane to the outlandish. Some believe the perpetrator was someone known to the family, possibly a disgruntled employee or a jealous acquaintance. Others speculate that the perpetrator was a serial killer or someone with a personal vendetta against the family. The possibility of a random act of violence, fueled by mental illness or drug addiction, has also been considered.
One theory suggests the perpetrator was a drifter or homeless person who stumbled upon the house and saw an opportunity to rob the family. The meticulousness of the cleanup and the lack of forced entry might support this theory. Another theory suggests the perpetrator was motivated by a personal grudge against Mikio Miyazawa, potentially related to his business dealings.
The messages left behind, particularly the English phrase “I’m sorry,” have added to the mystery. Some interpret the message as a sign of remorse, while others believe it was a deliberate attempt to mislead investigators. The inclusion of English, a language not typically used by the family, has fueled speculation about the perpetrator’s background and motives.
