Podcast host Ashley Flowers introduced the controversial investigative report, "Drivers High," as the basis for a major alternative theory in the Setagaya Family Murders case. Published 15 years after the incident, the author, Syushi Ikuta, concluded that the victims were likely killed by a hired hitman, possibly a former South Korean soldier, rather than during a botched robbery. The podcast highlighted the book's research regarding the killer's specific DNA markers and the context of the family's large compensation payout, finding the evidence compelling.
Episode: INFAMOUS: The Setagaya Family Murders
It was published 15 years after the murders and presented a new theory that the killer was a hired hitman, possibly a former South Korean soldier, connected to the family's large compensation payout.
In it, he lays out years of research, research that has led him to a conclusion no one really sees coming.
He doesn't think that the Setagaya killer is a skater kid, nor does he think it's a botched robbery. He thinks that whoever killed the Miyazawa family was a hired hitman, specifically a former member of the South Korean army.
But I read in Japan Today that the book lays out several pieces of evidence that point to the killer having a connection to the Korean peninsula, which again includes their DNA.
According to this article, their DNA has this specific marker that occurs in one out of every 13 Japanese people, one out of every 10 Chinese people and around one out of every five Koreans.
So statistically speaking, they're more likely to be Korean.
