Episode 140:
Slept With Mom’s Friend, Murdered His Own Dad,The Sickest Family Ever
At 7 a.m. on April 17, 2023, a man walking through an alley in Miyagi, Japan, spotted what he thought was a homeless man sleeping on the ground. Getting closer, he realized the body was stiff, the blood beside it already dried. The victim had a single, nearly seven-inch stab wound to his side — one deep enough to fatally damage his organs. His phone lay untouched beside him, and a trail of blood led away from the scene toward a nearby house, suggesting he'd been attacked inside and tried to flee. The dead man was identified as 54-year-old Ryuichi Murakami, and his wallet was the only thing missing — an oddly selective theft for what police quickly suspected wasn't a robbery at all.
Investigating Ryuichi's finances, police found that roughly $120,000 had been withdrawn from his account and transferred to his 31-year-old son, Yasuaki — money moved before anyone had even begun planning a funeral. On Ryuichi's phone, they also found a text sent two days before his death to his 25-year-old son, Naoya: a warning that he had evidence of "fraud" and was taking it to a lawyer within three days. Both sons appeared to have a motive. When police brought Naoya in, he confessed almost immediately — first to running an illegal extortion scam, then, after seeing a crime-scene photo of his father, to the murder itself. But what he confessed next was so strange that investigators realized they'd barely scratched the surface.
The Woman Who Groomed Both Sons
The story traced back fifteen years, to a pachinko parlor where two single mothers, Tomoe and Atsuko, first met. Tomoe was drowning — overwhelmed raising two young sons alone, she'd sunk into gambling addiction and stopped doing basic housework, leaving her boys bullied at school for wearing the same dirty clothes every day. Atsuko, sixteen years older than the elder son, stepped in like a savior: cooking, cleaning, buying clothes, becoming the stable presence their own mother couldn't be. But her kindness was calculated, and she groomed each son differently. By 2011, when the elder son Yasuaki turned 19, she had thoroughly gaslit him into marrying her — the family friend who'd essentially raised him — and nobody around them objected; from then on, he followed her with the blind devotion of a cult member. With the younger son, Naoya, she moved slower and darker: she manipulated him into sleeping with her by falsely claiming his own brother had hit her, preying on his sympathy, and years later, in 2020, she secretly built a fake online persona named "Jun," introduced as one of her old classmates with supposed psychic powers, to worm her way even deeper into Naoya's trust without him ever suspecting it was her.
The Mother Gaslit Into Selling Her Body
Once Atsuko had fully isolated Tomoe from any other support system, she pivoted to her real business: running honey-trap extortion scams, known locally as tsutsumotase, where a woman lures a man into a room before an accomplice crew bursts in to extort him. When Tomoe's money eventually ran dry, Atsuko pitched prostitution as an easy fix, framing it as something only the two of them needed to know about. She then built out a full operation — recruiting her own sister as a pimp to find clients online, and, chillingly, assigning Tomoe's own sons to enforce a daily earnings quota of $850, beating their mother if she came up short. It was a deliberate wedge: in the boys' eyes, Atsuko was the nurturing one, while their real mother was the source of trouble and punishment. For fifteen years, Tomoe sold her body night after night simply to keep meeting Atsuko's quota, all while being told it was the only way to pay off debts Atsuko had manufactured in the first place. Atsuko even orchestrated a sham marriage and later a remarriage to a man believed to have cancer, hoping to collect his life insurance after his death.
The Father Who Learned the Truth
By 2022, Tomoe had discovered Atsuko was plotting to kill her for a roughly $140,000 life insurance payout, and fled with help from her ex-husband, Ryuichi — the one person who eventually pieced together everything happening inside that house. Atsuko simply redirected her plan: with Tomoe out of reach, killing Ryuichi would still funnel his life insurance and inheritance to her husband, and by extension, to her. She began setting fires at Ryuichi's home — four attempted arsons before one finally succeeded in February 2023 — and when Ryuichi started building a legal case against her honey-trap operation using what he'd learned, she moved to eliminate him for good. Through "Jun," the psychic persona Naoya idolized, she delivered her real message: Ryuichi had cursed his sister-in-law with a fatal illness, and only killing him would save her life. Naoya didn't hesitate. He invited his father to a final family dinner, then stabbed him after everyone else had left.
Final Thoughts
Police eventually traced the "Jun" account and discovered it had never belonged to a real person — it was Atsuko herself, using intimate details about Naoya's childhood that she'd learned over years to convincingly play a stranger who somehow knew him inside and out. Even confronted with proof, Naoya refused to believe his sister-in-law had deceived him, insisting to the end that killing his father had been entirely his own decision. He was sentenced to 20 years in prison. Atsuko, revealed as the mastermind behind fifteen years of forced prostitution, honey-trap extortion, and her father-in-law's murder, received 28 years. Her husband Yasuaki, her sister, her ex-husband, and his wife were all convicted as accomplices with lesser sentences. In the end, the man who tried hardest to protect his sons from her — dragging himself out of his own home with his dying breath so his son wouldn't be found standing over his body — was the one person Atsuko never managed to fully control.
Atsuko spent fifteen years studying exactly what each family member was missing — affection, belonging, a sense of purpose — and manufactured a fake person to fill each void, including a fictional prophet who eventually convinced Naoya to murder his own father. Do you think Naoya's twenty-year sentence was fair given how long and how deliberately he'd been manipulated, or should the courts have weighed his brainwashing more heavily?
