אודות פרק זה
In August 1996, John Hartenfeld drove into the mountains of northern New Mexico for a solo fly fishing trip and never came home. His Toyota 4-Runner was found two months later on remote ranch land — every fingerprint wiped from the vehicle. His credit card had already been used, four days after he vanished, to buy a small and troubling amount of two-stroke fuel. Private investigators and law enforcement both concluded foul play. No one was ever prosecuted.
John's son James Hartenfeld is a Portland comedian who has spent most of his adult life with this unresolved wound. He joins us to talk about the moment as a kid when he searched under beds and in closets hoping his dad was pranking him, about the phone call his dad made to a close friend reporting that someone was messing with his car — days before he disappeared — and about a jaw-dropping development that happened just weeks before this recording: New Mexico cold case investigators found remains in the area where John vanished, and they need James's DNA.
James is also building My Little Cold Case, a six-episode documentary series about his father's disappearance. It's a project designed for the families that most cold case content ignores — the ones with no ending, no arrest, no resolution. Just a missing person and a family still waiting.

Every Unsolved Case Deserves a Voice.
Somewhere right now, a family is waiting for answers. Not the famous cases that dominate true crime podcasts or fill network television specials — but the other cases. The ones that slipped through the cracks of media attention. The ones where a name was forgotten before it ever had a chance to be remembered.
That's exactly why TheColdCases.com exists.
We are building the most comprehensive repository of lesser-known cold cases the internet has ever seen — a dedicated, searchable archive where forgotten victims finally get a permanent home. Where their names, their faces, and their stories are preserved with the dignity and urgency they deserve. Where investigators, journalists, amateur sleuths, and compassionate strangers can connect the dots that time tried to bury.
But we can't do this alone.
This work takes time, research, resources, and an unwavering community of people who refuse to let the forgotten stay forgotten. Every case we document is hours of careful, respectful work. Every profile published is a renewed chance for justice.
You are the missing piece.
