On Sunday, new details around the shooting emerged from text messages between local security units, obtained by the Republican senator Chuck Grassley and published and verified by the New York Times, including that local law enforcement had spotted the shooter 30 minutes earlier than what officials had previously said.
The published text messages show that a local countersniper first noticed a man, who was later identified as Crooks, loitering in the area where the countersnipers were set up more than 90 minutes before the shooting occurred.
The Times reported that at 4.26pm, the countersniper alerted his colleagues of Crooks, and that he had parked near their vehicles and was sitting on a picnic table near the warehouse, where several countersnipers were, outside the fenced area of the grounds where Trump would be appearing later.
The countersniper told his colleagues that Crooks knew they were there and saw him leaving with his rifle.
One of the countersnipers took pictures of Crooks and the photos were shared in a group chat and another text went out among the local officers at 5.38pm, saying they should inform the Secret Service, per the New York Times.
“Kid learning around building we are in. AGR I believe it is. I did see him with a range finder looking towards stage. FYI. If you wanna notify SS snipers to look out. I lost sight of him,” read one of the texts, accompanied by photos of Crooks.
One of the two remaining countersnipers reportedly ran out of the building attempting to keep eyes on Crooks until other law enforcement arrived, per Butler County officials, but Crooks ran off, taking a backpack with him.
At 6pm, one officer in the group texts guessed that Crooks was moving toward the back of the warehouse complex and away from the event, the Times reported. But instead, Crooks climbed on to a building in the complex closest to the stage.
At 6.11pm, Crooks began firing, grazing Trump’s ear, killing a rally-goer and injuring several others. Moments later, Crooks was shot and killed on the roof of a warehouse that was connected to the one the countersnipers were stationed in.
The newly released messages also suggest that the shooter was often one step ahead of security forces and law enforcement.
