Chain of Survival: How a Team of Strangers Brought Ronald Brock Home

Thursday, August 20, 2026

When Ronald Brock collapsed at his business on January 5, the odds were not in his favor. Sudden cardiac arrest kills the vast majority of people it strikes outside a hospital. But Brock is alive today, and fully recovered, because of a chain of people who each did their part, starting long before the fire department ever arrived.

Chain of Survival: How a Team of Strangers Brought Ronald Brock Home

It began with a phone call. Brock's business partner, Tim Coleman, dialed 911 and found himself on the line with Firefighter Roee Losycer, a dispatcher with Metro Fire Communications. In that moment, with a life on the line and no medical training of his own, Coleman needed someone to guide him. Losycer did exactly that, walking him step by step through hands-only CPR and keeping him steady and focused until help arrived.

"This is the piece of the story people don't always see," said Chief Jaime Moore. "Long before our engines pull up, the outcome is already being shaped by a dispatcher's voice on the phone and a bystander willing to act. Mr. Coleman didn't hesitate, and Firefighter Losycer gave him exactly what he needed to save his partner's life."

When Engine 104 and Rescue Ambulance 104 arrived, they took over a patient in full cardiac arrest. Over the course of the response, crews delivered high performance CPR, deployed a LUCAS mechanical compression device, initiated advanced life support, and delivered four defibrillation shocks as Brock cycled in and out of arrest. Through it all, the crew held to the fundamentals of resuscitation, precise, sustained, and relentless, until Brock achieved return of spontaneous circulation before he ever reached the emergency department.

He walked away with a full recovery. 

Stories like this are rare not because the skill isn't there, but because the timing so rarely lines up. A dispatcher has to coach clearly. A bystander has to be willing to act. Crews have to execute without hesitation. Every link in that chain has to hold. On January 5, every one of them did.

"We don't often get to see how these calls end," Chief Moore added. "Most of the time we treat, we transport, and the story continues somewhere out of view. This time, we got to close the loop, and the ending is the one we train for every single day."

The department extends its gratitude to Tim Coleman for stepping up when it mattered most, to Firefighter Roee Losycer for his composure and skill on the radio, and to the crews of Engine 104 and Rescue Ambulance 104 for the advanced care that carried Ronald Brock home to his family.
