HOUSTON — The entries are handwritten in a rushed scrawl and begin mundanely enough: “On location, setup” and “meet with (police) liaison.”

But as the situation deteriorated Friday at Astroworld Festival, entries in a Houston Fire Department Activity Log quickly turned from troubling — “Participants using bolt cutters to get in” — to harrowing — “Unconscious female in middle of crowd” — to deadly — “Reported cardiac in progress.”
