Welcome to the Chupacabra Attack Lab.

You're here because you've seen something in the field that didn't match the textbook. Puncture wounds too clean. Blood loss too complete. Veterinary reports that don't add up. Good — that instinct is why you enrolled.

What Wound Pattern Mastery will do for you:

• Train you to document and classify livestock wound patterns with forensic rigor

• Give you a complete conventional predator catalog so you can rule out coyotes, mountain lions, feral dogs, eagles, and bears with confidence

• Teach you the chupacabra attack signature — the core indicators that separate anomalous kills from everything else

• Equip you with a Decision Matrix that produces defensible field reports

How to move through the material:

1. Start with Module 1. The foundations are non-negotiable — skip them and your field reports will have holes.

2. Complete modules sequentially. Each builds on the last.

3. Use the Field Analyst Chat to post questions, share field observations, and submit cases for weekly live critique.

4. Check Case Updates for new case files, pattern alerts, and course announcements.

Weekly Live Critique: Every week I review student-submitted cases live. If you have a case from the field, submit it in chat with full documentation. This is where you'll learn the fastest.

The field doesn't care about your credentials. It cares about your methodology. Let's build yours.

If you work in livestock loss assessment, you've seen the default diagnosis: "coyote." It's the path of least resistance for vets and wildlife officers who aren't trained in differential wound analysis. Here are three patterns that routinely get misattributed — and what the evidence actually points to.

1. Clean paired punctures with minimal tissue disruption

Coyotes tear. Their jaw mechanics produce ragged, lateral wound channels with significant tissue displacement. When you see paired punctures at consistent 28-35mm spacing with minimal surrounding damage, you're not looking at a canid attack. The wound is too precise and the spacing too uniform. This pattern appears repeatedly in anomalous livestock death clusters across northern Mexico, southern Texas, and Puerto Rico.

2. Complete exsanguination without proportional external bleeding

A coyote kill bleeds. Extensively. When necropsy reveals near-total blood loss but the scene shows minimal pooling or spatter, the predator-prey interaction model breaks down. Conventional predators don't have the mechanism for this. If your scene documentation shows dry ground under a fully exsanguinated animal, you need to look beyond the standard catalog.

3. Absent defensive markers on the livestock

Prey animals fight. They kick, they run, they vocalize. Coyote attacks produce trampled ground, scattered hair/wool, broken fencing, and alarm responses from nearby animals. When none of that exists — when the kill is surgically quiet — the behavioral profile doesn't match any conventional predator in the Americas.

What this means for your fieldwork: If you're documenting livestock losses and these patterns show up, running it through a standard predator checklist will give you a false match. You need a differential diagnosis framework built for anomalous cases.

That's exactly what we teach inside Wound Pattern Mastery. The full course covers conventional predator catalogs, chupacabra attack signatures, blood-loss anomaly analysis, and a Decision Matrix for writing field reports that hold up under scrutiny.
