Which officers have been officially recognized as dying in connection with the Jan. 6 attack, and what were the official causes of death?

1. Brian Sicknick — the most prominent case and the medical examiner’s ruling

Officer Brian Sicknick, a U.S. Capitol Police officer who collapsed after being engaged on the front line during the riot, was long the focal point of debates about Jan. 6 fatalities; the D.C. medical examiner ultimately ruled his death to be by natural causes, identifying strokes and stating that “all that transpired” on Jan. 6 influenced his death, a finding that undercut homicide prosecutions tied directly to his death even as family and supporters say the assault he endured contributed to it ^{[1] [2] [4]}.

2. Officers honored posthumously — recognition versus cause-of-death clarity

Congress and others have posthumously honored several officers who responded to Jan. 6 — including U.S. Capitol Police officers Howard Liebengood and Billy Evans and Metropolitan Police Department Officer Jeffrey L. Smith among those named in ceremonial recognitions — but public sources included here note those honors without uniformly reporting medically or legally detailed cause-of-death findings for each officer in the same manner as Sicknick’s case ^{[1] [5]}.

3. Officer Jeffrey L. Smith and administrative findings on duty-related death

At least one officer’s death has been the subject of administrative review that linked a Jan. 6 injury to a later death: a board concluded that “Officer Smith sustained a personal injury on January 6, 2021, while performing his duties and that his injury was the sole and direct cause of his death,” a determination that produced survivor benefits for his widow and reflects an official channel for recognizing deaths tied to the riot even when criminal homicide charges were not pursued ^[3].

4. Suicides and later deaths — a contested tally and unanswered specifics

Reporting compiled around the five-year mark notes that more than 140 officers were wounded on Jan. 6 and that several later died, including four officers who died by suicide within seven months of the attack, but the reporting in the supplied sources aggregates these later fatalities without naming all individuals or detailing every medical or legal finding, leaving some official connections framed administratively or politically rather than uniformly adjudicated in criminal or forensic reports ^{[6] [7]}.

5. Disputed narratives and political friction over which deaths “count”

The question of which officers “died in connection with Jan. 6” is politically fraught: the Trump White House at one point advanced a disputed claim that “zero law enforcement officers lost their lives,” a position sharply contradicted by family members, congressional Democrats and many news reports; that dispute underscores both the legal complexity of tying a later death to on-the-job injuries and the political incentive to downplay or amplify those linkages ^{[2] [8] [9]}.

6. What the available records do — and do not — show

Available public records and reporting make clear that Officer Brian Sicknick’s death was ruled natural (strokes) with contributing factors tied to Jan. 6, that at least one officer (Smith) received an administrative finding that his Jan. 6 injury was the sole and direct cause of his death, and that multiple other officers who responded have been honored or counted among later fatalities (including suicides), but the assembled sources do not provide a single, unambiguous forensic or prosecutorial accounting for every individual law-enforcement death alleged to be connected to the attack ^{[1] [3] [5] [7]}.
