Thomas Matthew Crooks' father was seen in public on Monday for the first time since his son opened fire at former President Donald Trump's rally in Butler, Pennsylvania. The 20-year-old gunman was killed by snipers after injuring several individuals at the event.
Investigators have been visiting Crooks' family home in suburban Pittsburgh as they work to determine a motive for the shooting. The father, identified by locals, declined to comment and stated that they would release a statement through legal counsel.
