Crooks was seen at least twice by members of the emergency services unit team from Beaver County 26 minutes before he rained bullets on the Pennsylvania rally crowd, wounding former President Trump and two others and killing an ex-fire chief.

According to WPXI sources, the Beaver County cops noticed a suspicious man on the roof and took a picture of him and reported it around 5:45 p.m. The man in the photo was later determined to be Crooks. It was not immediately known if he had his rifle in the photo.

Another source told the outlet that a law enforcement officer spied Crooks on the rally grounds and called it in as a suspicious person, the officer including his own photo with the report.

About 26 minutes after the ESU member’s photo was presented to law enforcement, Crooks opened fire from the building’s rooftop before being killed seconds later by a Secret Service sniper.
