The episode begins with Mr. Ballin recounting a seemingly straightforward missing person case that spirals into a complex web of crime and manipulation.
Notable Quote:
“In 2011, a police officer spotted a woman on a busy street in Japan and he couldn't believe what he was seeing…” ([02:36])
2. The Missing Person Report
Miyoko Sumida, a 63-year-old woman from Amagasaki, Japan, reports her neighbor, Kai Oe, missing. Initially, the police believe there's a rational explanation for Kai's disappearance.
Notable Quote:
“…the officer assured Miyoko that he would file a report and the police would look into this right away. But the Officer also said that very likely there was a rational explanation here for why her friend had left.” ([03:31])
3. Discovery of the Body
A week and a half later, a warehouse crew discovers an unmarked metal drum containing the decomposed body of Kazuko Oe, Kai’s mother. The gruesome scene baffles Officer Sato, who suspects Yakuza involvement due to the method of disposal.
Notable Quote:
“Inside the drum was the twisted body of a dead woman… someone had poured cement inside the drum, and it had hardened and partially encased the woman's lower body.” ([06:45])
4. Investigation Begins
Officer Sato delves into the case, initially suspecting Yakuza ties. However, community outreach yields little, as the Yakuza had been laying low following a police crackdown.
Notable Quote:
“Sato knew there were yakuza groups in the city… but this didn't look anything like a domestic violence killing.” ([10:15])
5. Unveiling Kai Oe's Whereabouts
Contrary to the missing person report, Kai is found hiding in Osaka under a fake name. Her sudden reappearance without explanation raises suspicions.
Notable Quote:
“Kai had not been missing at all… she had been hiding out there using a fake name.” ([14:22])
6. Confronting Kai Oe
Sato confronts Kai, who appears frail and evasive. Her nervous behavior and inconsistent statements heighten the mystery, suggesting she knows more than she reveals.
Notable Quote:
“She looked like a corpse… she was rail thin and her eyes seemed hollowed out in her face.” ([20:10])
7. Gathering Witness Testimonies
Neighbors and a young couple provide fragmented accounts of witnessing Kai and her family abusing Kazuko. However, cultural norms in Japan hinder deeper investigation into domestic matters.
Notable Quote:
“They saw Kai, her sister and her brother-in-law, and their daughters beating Kai's mother, Kazuko.” ([24:05])
8. A Breakthrough Tip
An anonymous call leads Sato to suspect that Kai’s family is under the influence of a powerful Yakuza gang. Financial records reveal suspicious transactions linking the family to organized crime.
Notable Quote:
“…the family had made repeated big payments at regular intervals… a connection to the Yakuza.” ([26:45])
9. The Shocking Revelation of Miyoko Sumida
As investigations progress, it is uncovered that Miyoko Sumida is the clandestine leader behind multiple murders orchestrated through manipulation and psychological control. Her methods involve gaining trust, creating dependency, and enforcing obedience through fear and violence.
Notable Quote:
“Miyoko was more like a serial killer and a cult leader… she used mind control to gain power over them.” ([32:50])
10. The Final Unraveling
Miyoko's manipulation results in the murder of Kazuko Oe by her own daughter, Kai. Upon realizing Kai's conflicting emotions, Miyoko's tight grip falters, leading to Kai’s escape. Miyoko is ultimately charged with multiple murders but dies under mysterious circumstances in custody.
Notable Quote:
“Miyoko strangled herself with her own clothes and died in her cell… some people refuse to believe that Miyoko is actually dead.” ([40:30])
11. Aftermath and Legacy
The case concludes with Miyoko's notorious legacy in Japan, feared as “Grandma Piranha” and “the Demon.” Despite her death, suspicions linger about her potential escape, leaving the community unsettled.
Notable Quote:
“Miyoko would come to be known in Japan by names like the Killer, Grandma Piranha, and the Demon.” ([43:15])
