Which high-profile crimes have been linked to QAnon followers since 2017?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
Since 2017, reporting and compiled databases tie QAnon adherents to a range of high‑profile crimes including at least one fatal shooting, multiple murders and attempted murders, armed standoffs, a terrorism conviction for a Hoover Dam blockade, kidnapping plots and widespread participation in the Jan. 6 U.S. Capitol attack [1] [2] [3] [4]. Major outlets and research groups document specific cases — for example Anthony Comello’s killing of Gambino boss Francesco Cali (linked to QAnon in reporting) and the 2018 “Pizzagate” shooting and subsequent conviction of John Maddison Welch — while aggregated tracking counts several murders and dozens of violent incidents [5] [6] [7] [2].
1. The headline crimes journalists point to
Reporting and reference works consistently list a cluster of headline incidents: the Pizzagate‑era armed attack on Comet Ping Pong in which John Maddison Welch fired a rifle in 2016 and was later sentenced (an antecedent to QAnon) and the 2019 killing of Francesco “Franky Boy” Cali by Anthony Comello, who displayed a Q symbol in court and whom prosecutors tied in reporting to Q‑inspired delusions [7] [5]. Academics and news outlets also highlight armed standoffs — notably the Hoover Dam blockade by an adherent who pleaded guilty to terrorism charges — and a string of kidnappings, attempted kidnappings and other weapons incidents tied to believers [3] [6] [2].
2. How researchers and NGOs count the violence
Groups compiling incidents use different methods but reach similar conclusions: the ADL cites START data linking QAnon to at least seven murders since 2017 and notes dozens more incidents of violence, kidnapping and public disturbance [2]. University and think‑tank studies and news databases trace scores of violent events and many of the people charged in the Jan. 6 Capitol attack as QAnon adherents, underscoring that the movement has been implicated across a range of criminal activity [4] [8].
3. The Jan. 6 connection: mass crime by believers
Journalistic and academic sources document that numerous people who subscribed to QAnon joined the January 6, 2021, attack on the Capitol; some were charged with federal crimes connected to the riot, and researchers say QAnon messaging helped inspire portions of the crowd’s expectations of a violent “Storm” or reckoning [9] [8]. University of Maryland and other tracking projects later cataloged many of those charged as Q followers and linked the conspiracy’s apocalyptic rhetoric to the mobilization [10] [8].
4. Varied motive patterns: delusion, political zealotry, lone actors
Available reporting shows heterogeneity among offenders: some were lone actors acting on specific delusions (e.g., believing public figures were part of a child‑trafficking cabal), others joined collective events fueled by political anger, and some mixed Q claims with other extremist ideologies like sovereign‑citizen views [5] [11]. Researchers note mental‑health and trauma patterns among some offenders, but sources caution against conflating all adherents with violent actors [10].
5. Geographic spread and international echoes
While most high‑profile criminal cases cited are U.S.-based, QAnon‑linked behavior has surfaced abroad — including dramatic civic disruptions led by self‑styled figures such as Canada’s Romana Didulo whose followers were reported to receive violent directives — showing the theory’s migration from 4chan into global networks [10] [1].
6. Disagreement, limits and provenance of the links
Not every violent incident committed by a person who consumed QAnon content is straightforwardly “caused” by the movement; several outlets flag that co‑occurring factors (mental illness, local grievances, other ideologies) complicate causal claims, and some crimes predate or only tangentially relate to Q messaging [6] [7]. Reporting and databases differ on counts and thresholds for “linked to QAnon,” so headline numbers — “at least seven murders” (ADL/START) versus broader tallies of “scores of violent incidents” (NYT) — reflect methodological differences [2] [4].
7. Why these cases matter to the public record
Journalists and analysts argue these incidents transformed QAnon from an online curiosity into a demonstrable public‑safety problem: they prompted FBI warnings about potential domestic terrorism, platform takedowns, and academic efforts to map radicalization pathways [4] [8]. The crimes provide concrete examples of how online conspiracies can translate into offline harm without proving that most believers become violent [2] [4].
Limitations: this summary relies only on the supplied reporting and compilations; available sources do not mention every alleged QAnon‑linked incident nor offer a single, universally accepted tally, and some incident descriptions in aggregations reflect contemporaneous media accounts rather than final legal findings [6] [2] [4].
