January 2026 Update

I'm making my research publicly available and moving all content to Substack. I've also decided to write a book about the Columbine investigation. But this is not another Columbine book. This book is a page-turner even for seasoned researchers who thought there was nothing left to know.

Subscribe to The Columbine Case on Substack for basic research content and to be notified when the book is complete!

Be sure to subscribe to my main research publication True Crime: Case Reopened below for a more in-depth look at the case. This is a collaborative publication with RJ Sykes - the investigator blowing the whistle on the Jeffrey Dahmer case.
