Thomas Matthew Crooks, the man who opened fire during former President Donald Trump’s rally at the Butler Farm Show grounds on July 13, died of a “gunshot wound to the head,” according to the Butler County coroner.

A coroner’s report released Friday morning, Aug. 2, lists Crooks’ manner of death as homicide.

Crooks was shot and killed by a Secret Service counter-sniper, but not before he fired off eight bullets, killing one spectator, injuring two others, and grazing Trump’s right ear.
