Welcome to the Field Guide This is The Investigator's Field Guide — a running collection of real investigative material, pulled straight from the same sources actual investigators train on: crime scene guides, interview manuals, homicide procedure references, case studies. There's no set order here. One entry might break down an interview technique. The next might be a piece of crime scene protocol, or a mindset shift pulled from a real case. You're not working through a curriculum — you're picking up real tradecraft, one piece at a time, the way it actually gets learned on the job: a little at a time, from wherever the next lesson comes from. HOW THIS WORKS - New entries get added as we pull them from the source material — no fixed schedule, just steady drops. - Every entry follows the same format: the concept, a real scenario, why it matters, how to apply it. - This is the open floor. Come back whenever — there's always something new to pick up. WHERE TO START Read Tactic File #TF-001 — The Free Narrative Funnel, pinned below. It's the first entry in the series. BONUS — WANT THE FULL SYSTEM? The Field Guide gives you the pieces. 90 Days to Investigator is where they connect — a structured, 90-day, day-by-day program that builds the full investigative mindset, not just isolated tactics. Module 1 is free to try. KEY TAKEAWAY Every visit here should leave you a little sharper than the last. That's the only job this classroom has. — Chris Coco Coco Case Files

For the last year, this page has been a little all over the place — I’ll own that. But I’ve spent the last few months building something I actually believe in: 90 Days to Investigator, a real day-by-day training program built from 26 years of actual law enforcement work — not TV tropes, not recycled true-crime trivia. Real LEO guides, real case logic, a real running case you work through yourself. Module 1 is free, right now, for everyone. Fifteen days of real foundational training — the investigative mindset, the frameworks, the way trained investigators actually think. No catch, just start with Case File #001 in the Classroom. If it hooks you — and I think it will — the rest of the program (Modules 2 through 6: Observation, Interviewing, Crime Scene Work, Case Logic, and Case Closed) is available as a one-time purchase. $27, everything included, no subscription. That price is Founding Detective pricing — it goes to $149 once the first 75 spots are gone. After that, this is the last time it’s ever this price. 👉 Start with Case File #001 (free) in the Classroom. 👉 Ready to go all in? Grab the full program here for $27 while Founding Detective pricing lasts. No detective works alone — glad to have you back, or glad to have you here for the first time. — Chris Coco
