In American law enforcement, EOW stands for “End of Watch.” It is the moment an officer’s shift ends. It is also, in its heavier use, the date an officer died in the line of duty, printed beneath a name on memorial walls and spoken aloud at funerals.
The Everyday Meaning on Shift
Every patrol shift has a start and a finish. Officers go “on watch” when they check in and reach their end of watch when they sign off. Many departments still use ten-codes for routine radio traffic, and 10-42 specifically means “ending tour of duty.”1IAED Journal. The Call That’s Hard to Make A dispatcher logs the time, the unit number drops off the board, and the next shift takes over. Nothing more than clocking out.
That ordinary origin is what makes the term land so hard in its other use. The same three letters that end a Tuesday afternoon become permanent when they follow a date on a plaque.
EOW as a Line-of-Duty Death
When an officer is killed while performing official duties, the date of death is recorded as their End of Watch. This is the meaning most people encounter in news coverage, on department social media, and on memorial pages.
The FBI’s Law Enforcement Officers Killed and Assaulted (LEOKA) program sorts these deaths into two categories: felonious killings, where an officer is intentionally killed by another person, and accidental deaths from events like vehicle crashes, training incidents, or falls during pursuits.2Federal Bureau of Investigation. Statistics on Law Enforcement Officer Deaths in the Line of Duty To be counted, the officer must have been duly sworn with full arrest powers, acting in an official capacity, and the death must be directly tied to the incident. Natural causes, suicide, and deaths from personal disputes unrelated to duty are not included. In 2023, 60 officers were feloniously killed and 34 died from accidental causes while on duty.
The federal Public Safety Officers’ Benefits program uses a related standard, requiring the death to be the “direct and proximate result of a personal injury sustained in the line of duty.”3GovInfo. Public Safety Officers’ Benefits Program Chronic disease or occupational stress alone generally do not qualify unless a traumatic injury was a substantial contributing factor.
How an Officer’s End of Watch Is Marked
Several traditions turn the abbreviation into a ceremony.
The Last Radio Call
The most recognizable is the last call. A dispatcher reads the fallen officer’s badge or unit number over the radio. Silence. The dispatcher calls again, and again there is no answer. After the third unanswered call, the dispatcher announces that the officer is end of watch, often closing with words like “gone but not forgotten” or “rest in peace, we’ll take it from here.”1IAED Journal. The Call That’s Hard to Make Scripts vary by department, but the structure is consistent enough that officers across the country recognize it immediately.
Mourning Bands
Officers wear a solid black mourning band across their badge after a line-of-duty death. On most badge shapes the band runs horizontally across the center; on star-shaped badges it runs diagonally from the 11 o’clock to 5 o’clock position. When the death is within an officer’s own department, the band stays on for 30 days. For a neighboring jurisdiction’s loss, officers wear it from the date of death through the day of burial.4Officer Down Memorial Page. Mourning Band Protocol
Funeral Honors
Law enforcement funerals routinely draw hundreds of uniformed officers from departments across the region and sometimes the country. Processions include motorcycle escorts and patrol car formations. Flags at the department, and often at government buildings, fly at half-staff. Many departments also grant a posthumous promotion to the next rank, which can carry practical consequences for survivor benefits in some jurisdictions.
National Remembrance
The Officer Down Memorial Page is an online memorial dedicated to the more than 27,000 law enforcement officers who have died in the line of duty since the nation’s founding, with an individual page for each officer where family, colleagues, and the public can leave tributes.5Officer Down Memorial Page.

May 15 is Peace Officers Memorial Day, established by federal statute and observed through an annual presidential proclamation. The law directs that the U.S. flag fly at half-staff on all government buildings that day and invites state and local governments to do the same.6Office of the Law Revision Counsel. 36 USC 136 – Peace Officers Memorial Day The week around it is National Police Week, when thousands of officers travel to Washington, D.C. for candlelight vigils, wreath-laying ceremonies, and the reading of names newly added to memorials.
What an EOW Triggers for a Family
An officer’s End of Watch sets federal benefits in motion. The Public Safety Officers’ Benefits program pays a one-time, lump-sum death benefit to survivors of public safety officers killed in the line of duty. For deaths in fiscal year 2026, running October 1, 2025 through September 30, 2026, that benefit is $461,656.7Bureau of Justice Assistance. Benefits by Year – PSOB If a surviving spouse and children exist, half goes to the spouse and half is divided equally among the children; if there is no spouse, the children receive the full amount.
The program also provides educational assistance for the children and spouses of fallen officers, set at $1,574 per month of full-time study for fiscal year 2026.7Bureau of Justice Assistance. Benefits by Year – PSOB Both the death benefit and educational assistance are exempt from federal income tax. Many states add their own lump-sum death benefits on top of the federal payment, and some reimburse funeral costs separately. Amounts vary by jurisdiction.
Concerns of Police Survivors, known as C.O.P.S., serves spouses, children, parents, siblings, and co-workers affected by a line-of-duty death. Between 140 and 160 officers die in the line of duty each year, and the organization runs counseling, peer support, scholarships, and survivor retreats at no cost to families.8Concerns of Police Survivors.
