Which individuals died on January 6 2021 and what were the official causes of death?

1. Immediate fatalities on January 6 — who died that day and how official reports record them

On January 6 itself, four people died whose names and causes were later reported by local and national authorities: Ashli Babbitt, a rioter who was shot inside the Capitol as she attempted to climb through a broken door into the Speaker’s Lobby; Rosanne Boyland, initially described as crushed by the crowd but whose death the D.C. medical examiner later attributed to an accidental overdose of amphetamines (her prescribed ADHD medication); and two other attendees who died of medical events — one from a heart attack and another from a stroke ^{[6] [1] [2] [3]}.

2. The fifth death and the medical examiner’s finding — Capitol Police Officer Brian Sicknick

Capitol Police Officer Brian Sicknick collapsed the evening of January 6 and died on January 7; the D.C. medical examiner ultimately ruled his death to be from natural causes, specifically two strokes, while noting family beliefs and public debate about whether the events of the day contributed to his condition ^{[2] [4]}.

3. Names tied to the official causes in public reporting

Media and official reporting identify the rioter shot as Ashli Babbitt (killed by a U.S. Capitol Police officer), Rosanne Boyland (accidental amphetamine overdose as ruled by the D.C. medical examiner), Benjamin Phillips (reported in contemporaneous coverage as having died of a stroke while traveling with others that day), and Kevin Greeson (whose death was reported as a heart attack in multiple accounts); Brian Sicknick’s death was ruled natural causes (two strokes) by the medical examiner after he collapsed following the riot ^{[6] [1] [3] [2] [4]}.

4. Later law‑enforcement deaths, suicides, and administrative rulings

In the months after January 6 several police officers who had responded to the riot died by suicide, including Metropolitan Police Officers Kyle DeFreytag and Gunther Hashida in July 2021; other officer deaths by suicide and post‑riot medical events prompted administrative reviews, and in at least one case a retirement and relief board concluded an officer’s suicide was the direct result of injuries sustained on January 6 and therefore a line‑of‑duty death (Jeffrey Smith’s case) — underscoring that the casualty count connected to the event expanded as agencies assessed mental and physical aftereffects ^{[4] [5]}.

5. Disputes, public perception, and official nuance

Public debate has centered on which deaths are “because of” the riot versus coincident or secondary; reporters, medical examiners, and government boards have not always spoken in the same shorthand — for example, Sicknick’s family and many observers said the assault he endured contributed to his collapse even though the medical examiner listed natural causes, and some officials and watchdogs track a broader set of deaths and injuries attributable to the attack, including later suicides among responding officers ^{[2] [7] [5]}.

6. What the sources collectively establish and where limits remain

Contemporary journalism and official records converge on a compact set of factual determinations: Ashli Babbitt was killed by a Capitol Police officer (a homicide in the sense of a shooting by police), Rosanne Boyland’s death was ruled an accidental amphetamine overdose, two attendees died of a heart attack and a stroke respectively, and Officer Brian Sicknick died the next day of two strokes as ruled by the D.C. medical examiner; beyond those determinations, attribution of causation (how much the riot directly precipitated each death) has been the subject of subsequent administrative reviews, family statements, and political debate, and standard public sources do not uniformly answer every causal nuance ^{[1] [2] [3] [4] [5]}.
