Host: Carter Roy
Date: April 3, 2026

Carter explores the origins, evidence, skepticism, and ongoing haunt of this unresolved mystery, focusing on the detectives who couldn’t let the case go—and the families still seeking the truth.

Key Discussion Points & Insights

1. The Origin Story: Patrick McNeil's Death

• Patrick McNeil, 1997: (06:25)
  • 20-year-old Fordham University student disappears after a night at the Dapper Dog Bar, NYC.
  • Witnesses see a car (with a man and woman) following him as he drunkenly leaves.
  • His body is found two months later in the East River, only in jeans, underwear, and socks.
  • Officially ruled a drowning, but Detective Kevin Gannon notes suspicious signs: marks around neck, burning on his head/back, and a lower blood alcohol level than expected.

“There were marks on his neck suggesting he had been bound, and charring on his head and back showing he may have have been burned. But the smoking gun was his blood alcohol level... Not as intoxicated as he reportedly was.”
— Carter Roy (09:39)

• Gannon’s theory: Patrick was drugged (possibly with GHB), abducted, murdered, and dumped in the river.

2. Emerging Patterns and National Connections

• Rise of the Theory (13:30)

  • After Patrick’s case, Gannon notices similar mysterious drownings in and beyond NYC, all ruled as accidents.
  • Many victims are young, athletic, white men, last seen drinking with friends; their bodies recovered from water—often with minimal decomposition.
  • Gannon teams up with Anthony Duarte and Professor Doc Gilbertson to investigate further.

• Midwest Cluster (16:20)

  • The pattern extends to Minnesota and Wisconsin, where similar unexplained deaths occur.
  • Gilbertson’s research at St. Cloud State University (with help from students) compiles a spreadsheet of matching cases across the Midwest.

• Formation of Nationwide Investigations (18:35)

  • Gannon, Duarte, and Gilbertson create a detective agency to systematically examine cold cases.
  • They note the repeat appearances of smiley face graffiti near dump sites—a potential calling card.

3. The Smiley Face Symbol as a Signature

• The Graffiti Marker (21:20)
  • The team finds smiley face graffiti near many sites (with variations: tongues, horns, added symbols).
    • E.g., the “evil happy smiley face man” variant in Iowa.
  • Other graffiti tags include terms like "Sinsinawa"—linked to locations or possible messages.

“A block away from where Scott's body was discovered, there was a piece of graffiti on the wall. A smiley face.”
— Carter Roy (20:34)

4. Challenges and Criticism

• Doubt from Law Enforcement & Academia (34:10)
  • Police and the FBI consistently reject the serial killer theory, calling most cases accidental drownings, usually alcohol-related.
  • The FBI’s statement:

    “To date, we have not developed any evidence to support links between these tragic deaths or any evidence substantiating the theory that these deaths are the work of a serial killer or killers.” (25:15)

  • The Center for Homicide Research (2010):
    • Points out inconsistencies in the graffiti.
    • Notes the smiley face is a common, unspecific tag.
    • Argues forensic evidence from river drownings is still possible to attain.
    • Suggests Gannon’s emotional investment clouds his objectivity.

5. Notable Victims and High-Profile Cases

• Christopher Jenkins, 2002: (27:45)

  • 21-year-old found face up (unusual for drownings) in the Mississippi after a night out in Minneapolis.
  • Initially ruled an accidental death, later changed to homicide after an inmate tips off police.
  • The case gains national attention, fueling wider interest in the Smiley Face theory.

• Matt Krasiewski, 2005:

  • Disappears from East Dubuque, Illinois; found in the Mississippi; connections drawn to "Sinsinawa" graffiti.

• Other locations:

  • La Crosse, Wisconsin, noted for a cluster of river deaths; police attribute many to dares, alcohol.

6. Ongoing Impact & Pop Culture

• The story goes viral—features in news, documentaries, and even fiction (e.g., "Smiley Face Killers" film by Bret Easton Ellis, 2020).
• Social media (like TikTok) keeps the theory alive, especially whenever a new unexplained drowning occurs—such as the 2025 Houston bayou deaths.

7. Lasting Questions & Legacy

• No case has conclusively linked any deaths to a "Smiley Face Killer" or group.
• Victims’ families are split—some grateful for renewed attention, others feeling misled.
• Gannon and Duarte continue to pursue the truth, undeterred by skepticism.

“Whatever the truth is, almost 20 years after Kevin and Anthony went public with their research, the Smiley Face killers theory still has a grip on the public consciousness.”
— Carter Roy (41:56)

Notable Quotes & Memorable Moments

• On the drive of the investigators:

  “Kevin personally financed a lot of their investigations. He even remortgaged his house to pay for their work. But he really believed they were onto something. If it could help the victim's loved ones, it was worth it.”
  — Carter Roy (20:14)

• On the skepticism and emotional toll:

  “The father of one victim said, I feel Kevin is like a SpongeBob. He latches onto the families, sucks the life out of them, and when he has nothing else to suck, he dumps them.”
  — Carter Roy quoting (41:12)

• On the openness of the mystery:

  “Unfortunately, we may never know exactly what happened to the men who died. It's a mystery that seems to defy explanation, but a coordinated network of serial killers is certainly a compelling one.”
  — Carter Roy (41:30)
