According to a new report from News 11, law enforcement sources told the outlet that leading up to the assassination attempt on Trump, killer Thomas Crooks was spotted on a roof almost 30 minutes before the incident took place. Even earlier, law enforcement spotted a suspicious-looking Crook on the grounds.

The shooting took place at 6:11 pm, and a member of Beaver County’s ESU team noticed a suspicious man on a nearby roof at around 5:45 pm. He had called it in and took a picture of Crooks. It was Crooks, but they didn’t know if he had a gun on him.
