About This Project

When an officer dies,
the clock starts instantly.

The family needs immediate support at the door, the department needs clear decisions in the chaos, and the community is already watching.

Because these tragedies are rare, most agencies lack institutional memory for a line-of-duty death. They are left navigating complex logistics, benefits, and protocols while processing overwhelming grief.

Aftermath bridges that gap. Built on thirty years of John Cooley’s field-tested protocols, it provides leadership and chaplains with the missing roadmap before crisis strikes.

Who it serves

  • Chiefs and command staff
  • Chaplains and peer support teams
  • Officers asked to lead

For any agency that loses one of its own — to line-of-duty death, suicide, trauma, or public loss.

Six domains, covered in advance

  1. Pre-planning
  2. Family care
  3. Death notification
  4. Funeral protocol
  5. Trauma response
  6. The chaplain’s role

The worst time to figure out what to do is when you are already in the middle of it.

About John Cooley

Thirty years.
Eighty funerals.
Nothing left to chance.

For a decade, Cooley served as the Officer-in-Charge of the LAPD’s Employee Assistance Unit — personally overseeing how the nation’s second-largest police department responded when one of its own was lost. In that role, he planned and conducted more than 80 police funerals and memorial services, including 21 line-of-duty deaths: 18 for the LAPD and three for neighboring California agencies.

He saw what worked. He also made mistakes — and he has never stopped thinking about them. In a field where every error is paid for by a grieving family or a department in crisis, those lessons became the most valuable thing he had to teach.

He believes a funeral can heal. That conviction — and everything it cost him to earn it — is what Aftermath exists to carry forward.

He took that knowledge
to departments across America

For years, Cooley traveled the country conducting seminars for chiefs, command staff, chaplains, and agency leaders — teaching what he had learned and, just as importantly, what had gone wrong. He covered the full scope: pre-planning, family care, death notification, funeral protocol, and departmental recovery. What the manuals leave out. What mistakes teach when manuals fail.

Crisis Checklists

A lifetime of experience, ready at a moment’s notice.

Sample pages from the Honoring the Fallen Walk-through Lead checklist

The Checklist – that humblest of quality-control devices is key in managing complicated, once in a lifetime events like a police funeral.

The equivalent to a pilot’s or surgeon’s checklist – a CRISIS CHECKLIST offers police leaders a lifetime of experience in ready to use checklist form.

Compiled by one of the nation’s foremost authorities on managing a police funeral, each checklist is designed to help police leaders master the myriad of decisions they face following a line of duty death.

Someone needs to care.
If not me, who?

The question John Cooley returned to in every planning meeting, every family notification, every funeral where something could go wrong and someone had to make sure it didn’t.
