Sources: Building where shooter fired at Trump rally was staging area for local law enforcement

BUTLER, Pa. (ABC NEWS) — The building where Thomas Crooks climbed onto the roof and opened fire was being used as the staging area for the local police tactical team, according to two law enforcement officials who spoke to ABC News.

Crooks’ attack, which took place during a high-profile public event, left several people injured and sent shockwaves through the community. The exact location of the tactical team within the building at the time of the incident remains unclear. Sources previously informed ABC News that the building had been swept, but investigators are now trying to determine whether roof access was properly secured.

In the chaotic aftermath, it was discovered that Crooks had gained access to the roof without using a ladder, raising concerns about potential security oversights.

The police tactical team, responsible for overseeing the crowd, was seemingly unaware of what was happening on the roof at the time. Investigators are now working to understand how Crooks managed to access the roof and carry out the attack despite the team’s presence in the building.

The community continues to grapple with the implications of the shooting, as authorities conduct a thorough investigation into the security measures and protocols in place during the event. The investigation into how Crooks managed to access the roof and carry out the attack is ongoing.
