The FBI have released photos of a potential suspect in the shooting of Charlie Kirk.
The individual was captured by security cameras in the area wearing sunglasses, a black hat and black long-sleeve shirt.
The FBI also announced a $100,000 reward in exchange for information leading to identification of the shooter.
Kirk was hosting a debate when the shooter fired from a building roof some distance away to the courtyard where the event took place.
In a video obtained by The Associated Press, an individual is seen running across the roof of a campus building.
In woods nearby, law enforcement officials recovered a high-powered rifle.
Investigators have said the shooter appeared to be college aged and able to blend in with the crowd.
