On September 6, 2024, Phoenix lost Police Officer Zane Tristan Coolidge. He was 29 years old, five years into his service with the Phoenix Police Department, and known in the public record by badge number 10914. His end of watch came through gunfire, leaving behind a silence that no badge, shift, or memorial can make whole.
The facts are stark, but they are not small. Officer Coolidge responded to reports of a larceny from a motor vehicle near 16th Street and McDowell Road. A man attempting to break into a vehicle opened fire after officers approached, according to the City of Phoenix. A public servant went toward a reported crime and never returned.
A Young Officer Still Giving His Years to Phoenix
Five years is long enough to understand the demands of police work, yet short enough to remind us how much future still stood before Zane Tristan Coolidge. At 29, he was not at the end of a completed story. He was in the living middle of one, continuing a profession built around answering other people’s emergencies.
The Phoenix Police Department entrusted Officer Coolidge with the responsibilities represented by badge 10914. That number identifies him in a department, but it cannot contain him. Behind it was a person who had given five years of his life to Phoenix, accepting the obligation to respond when others needed help.
There are losses that feel especially cruel because they interrupt a life still unfolding. Officer Coolidge’s death carries that particular heartbreak. His age makes the permanence difficult to grasp: 29 years, five years of service, and then a future erased in a few violent moments. The loss is not abstract. It is the loss of everything he would otherwise have had time to become.
The Call Became a Place of Irreversible Loss
The reported offense was a larceny from a motor vehicle—an incident that began as a call for service. According to the City of Phoenix, Officer Coolidge and another officer approached a man attempting to break into a vehicle near 16th Street and McDowell Road. The suspect fled on foot and opened fire on officers.
That sequence carries a terrible unfairness. Officers answered a report of property crime, approached a person they were trying to stop, and were met with gunfire. What began with an ordinary public-safety response became a fatal attack, and Phoenix was left to absorb a loss no explanation can repair.
Officer Coolidge was shot while responding, and gunfire became the cause of his death. Those words are clinical, but the reality behind them is not. A department lost one of its own. A 29-year-old life ended. The people who knew him, worked beside him, and counted on his return were forced to confront an absence created by violence.
What Phoenix Must Carry Forward
A police department is often described through its calls, units, and numbers, but grief does not move through a database. It moves through the empty space left by a colleague. It moves through the badge number 10914, now inseparable from the name Zane Tristan Coolidge and the date September 6, 2024.
The City of Phoenix has reported the circumstances of the shooting, but the most important truth is simpler: Officer Coolidge served Phoenix for five years, and that service ended because someone chose to answer a public response with gunfire. The anger is justified. No act of duty should demand that a young officer’s life be the price of answering a call.
Remembering him responsibly means refusing to reduce him to the manner of his death. He was a Police Officer with the Phoenix Police Department, a 29-year-old public servant who had devoted five years to the city. His life deserves more than the final violence that took it, even as that violence must never be minimized.

Phoenix will carry Officer Zane Tristan Coolidge’s name with the weight of a life taken too soon. His end of watch was September 6, 2024, but the meaning of his service did not end there. Five years of duty remain part of the city’s history, and badge 10914 remains tied to the officer who wore it.
The sorrow is permanent because the loss is permanent. Officer Coolidge should have had more years, more calls answered, and more life beyond the badge. Instead, Phoenix mourns a 29-year-old officer killed by gunfire while doing his job. His sacrifice should be remembered with gratitude, grief, and an unflinching recognition of how needlessly he was taken.
