The FBI’s latest disclosed records contain previously unpublished investigative material, including drone photographs taken months before the attack, Samsung phone communications, unusual online messages, forensic evidence and enquiries into Crooks’ contacts.
The documents reveal how investigators reconstructed his activities before the shooting, including aerial photography of Pittsburgh sports venues and other Pennsylvania locations. They also expose the limitations of heavily redacted investigative records.
Was Crooks planning the attack months in advance? Did his communications reveal anything suspicious? Why did investigators examine an unusual online conversation? And what evidence, if any, points towards accomplices?
Taylor Tailored investigates the records, explains what they establish and examines the unanswered questions surrounding one of the most consequential American political security failures in recent history.
