  • The DARK Case of the Strangler Who Mailed Police His Own Evidence for 30 Years
    May 23 2026

    In our first instalment of D.A.R.K Cases, we look at an event where for thirty years, a man named himself, signed his own letters to the police, and mailed them to the newspaper himself. Ten people dead in Wichita and Park City, Kansas. All within a few miles of each other, all approached the same way, all by the same hand. He went quiet for thirteen years. Then in 2004 he came back, sending nineteen communications in under twelve months, more than he had managed in the previous decade combined. He wanted to be known. He needed it. And in the end, a single floppy disk told police everything they needed.

    This is Case 001.

    DARK Cases is an investigative series reconstructing real criminal cases from around the world — one nation at a time.

    Case 001: The DARK Case of the Strangler Who Mailed Police His Own Evidence for 30 Years — Wichita, Kansas, USA.

  • My Goal Is To Cover One True Crime Case In Every Nation [Enter: The D.A.R.K. Cases]
    May 16 2026

    This is the preview of Detective Abroad Reconstructing Known Cases (D.A.R.K. Cases for short). A series where fictional investigator William Invisoler walks through real, documented criminal cases so we can understand how investigators actually think, follow evidence, hit dead ends, and find their way back. Every case is real. Every lead is documented. Every conclusion was reached by a real investigator. William is just the lens.

    This series exists because I'm writing a mystery novel and I refuse to write paper-thin detectives. I want the cases in my book to feel like they were built by someone who actually studied how investigations unfold. That's what this is. A research project, a storytelling experiment, and a training ground, all at once.

    Chapter Zero of my novel goes up Sunday. The first full DARK Cases episode drops Wednesday.
