Mass killings, 3+ killed in the United States

America's crime record

131

incidents, 2025 · Down 25% from 2024

Timeline

Incidents with three or more people murdered, with any weapon, in any circumstance: the federal definition of a mass killing (28 U.S.C. 530C(b)(1)(M)(i), from 2013), and the people murdered in them.

Source and method

CrimeDB's count from the murder records police agencies send the FBI, the homicide reports (SHR) and NIBRS together: where both describe one incident it counts once, with NIBRS's fuller details, and records an agency entered twice count once. The offender is not counted. Agencies that sent nothing are not in the count, nor is Florida for most years from 1988 to 2016. Never added to the 4+ or active shooter counts.

No rate. An incident is not something that happens to a person, so incidents take no rate per resident; the people killed have one, per 1 million residents.

FBI Supplementary Homicide Reports and NIBRS, merged by CrimeDB · Calendar year · 1976 to 2025

Every yearThe Supplementary Homicide Reports (SHR) master file and the NIBRS national master file are joined into one record. Mass killings, three or more killed: SHR records and NIBRS incidents that describe the same killing are linked into one incident, so none is counted twice.
1976Before NIBRS: every incident is an SHR record.
1976–1984These years come from the Murder Accountability Project copy of SHR, filling a gap in the Supplementary Homicide Reports (SHR) master file. CDE serves homicide reports from 1985 only. MAP's copy matches the FBI's files byte for byte for 1985 to 2016, so it stands in for the years before; the change of copy is a break.
1988The SHR holds no Florida murder records for 1988 to 1991 and 1997 to 2016, and Florida did not report to NIBRS then; counts there are floors.
1991NIBRS covers the agencies reporting to it, a minority before 2021: their incidents take NIBRS's richer fields (the day, location, each victim's relationship and circumstance); the rest stay SHR records.
2021The FBI builds the SHR from NIBRS from 2021, so nearly every incident is a linked pair; SHR gang circumstance codes break.
2022–2025The NIBRS state incident files and the NIBRS national master file hold the same records side by side. CrimeDB uses the NIBRS national master file; the other is kept as a check. The zips are the frozen snapshot the FBI's NIBRS tables were built from, 1% to 5% fewer incidents than the rebuilt master file (2025 equal). They check those tables.
2023Wisconsin, West Virginia, and Wyoming come from the NIBRS state incident files, filling a gap in the NIBRS national master file. The 2023 master file stops partway through Wisconsin and has no West Virginia or Wyoming rows, and the FBI has not reissued it (checked 2026-10-08). The normalized NIBRS records take those states' incidents from the zips.
2026Left out: the 2026 files are partial: built by the FBI on 2026-09-15, before the year ended.

All 5,163 people killed, 2017 to 2025, every year added. From 2017, the first year since 1986 that the homicide reports carry Hispanic origin for most offenders. Rates are per 1 million people in the group a year. From 2017 the homicide reports keep Asian and NHPI apart, like NIBRS; ethnicity in its own field, recorded for about 70% of people. Officers record race and ethnicity, often by sight or from a victim's or witness's account; where ethnicity is recorded, most Hispanic people are coded White (93% of Hispanic victims in states that record it well). People with a race and no recorded ethnicity are split by the stated rules (crimedb-ethnicity-rules-v2), the lighter part of each bar. Rate: people killed per 1 million people in the group; – means no rate for that group.

Hispanic is of any race; the other groups are not Hispanic. White+MENA includes Middle Eastern and North African people.

184 of the 1,436 incidents from 2017 to 2025 (13%) have no known offender, so no one from them is in the offender figures. Those with none, by kind: gang killings 33%, drug killings 15%, felony killings 18%, circumstance unknown 25%, family killings 0%.

Of these known offenders, 7% have no recorded race. They are in no group's rate, so each rate is a floor.

The homicide reports give a relationship for the first victim only; in NIBRS, which records every victim's, the first victim alone finds 84% of family killings, so family runs a little low where the homicide reports alone hold the incident. From 2017 the homicide reports keep Asian and NHPI apart, like NIBRS; ethnicity in its own field, recorded for about 70% of people. Officers record race and ethnicity, often by sight or from a victim's or witness's account; where ethnicity is recorded, most Hispanic people are coded White (93% of Hispanic victims in states that record it well). People with a race and no recorded ethnicity are split by the stated rules (crimedb-ethnicity-rules-v2), the lighter part of each bar. Rate: known offenders per 1 million people in the group; – means no rate for that group.

Of these known offenders, 14% have no recorded race. They are in no group's rate, so each rate is a floor.

How we count

Age: Age at the offense, in the same bands on every page.
Sex: Biological sex: female or male.
Race and ethnicity: Six groups, the same on every page. Hispanic is of any race; the other five are not Hispanic, so no one is in two.
Relationship: The victim's relationship to the offender, as police recorded it.
Counting once: Each person counts once in each row they fit, so rows can add up to more than the total.
Unknowns: Unknown is always its own row, and every share reads against everyone.
Small counts: Every count is shown, however small.
Marks on figures: When a figure is missing, the page says why.
Rates: Pages call it the rate: how many for every 100,000 people, or every million for rare events. It always sits beside its count, never in place of it.
Who reports: Police figures count only the agencies that sent records to the FBI.
