John McAfee and Champlain Towers South: who did what, and when (2019 to 2026)

As of 2026-10-02. Times are UTC. Miami was on daylight time (UTC-4) in June 2021 and Spain on summer time (UTC+2). Where only a date is reported the event is drawn hollow. NIST's "early June" is a range, drawn as a bar and marked as an inference for its edges. The collapse time is given as about 1:30 a.m. by NIST and 1:22 a.m. by other sources; both are shown. Quoted facts were read in the cited sources, as marked. No claim is made about any person beyond what those sources say.
