The FBI has released new footage of the suspect fleeing the scene after conservative commentator Charlie Kirk was shot at a Utah university on Wednesday.
In the video, a person can be seen running across the roof of a building, before jumping to the ground and escaping on foot.
Authorities previously released two images of a suspect wearing dark clothing, sunglasses and a baseball cap. The person of interest's identity has not been released.
The FBI said Thursday that a firearm and ammunition believed to have been used in the attack were recovered in the woods near the university.
The suspect remains at large, and a manhunt is ongoing.
