She wrote in a resignation letter that she takes “full responsibility for the security lapse.”Crooks’ motive has not been determined.Pennsylvania State Police Col. Christopher Paris, who heads the agency, told a House Homeland Security Committee hearing Tuesday that Crooks had been identified as suspicious before the shooting.Crooks had been spotted “milling about and he stood out to them because he never made his way to a point of ingress to the venue,” meaning Crooks was milling about but not trying to enter, and that Crooks was later seen with a range finder.Paris said the Butler County Emergency Services Unit, tasked with securing the building where Crooks fired from, relayed the suspicion and a photo of Crooks to the state police, which then passed along the message to the Secret Service.
