Attendees at the campus event where US conservative activist Charlie Kirk was fatally shot on Wednesday have described mass panic after a shot was heard. Kirk, 31, was killed after he was hit in the neck by a single bullet, which law enforcement believes came from a shooter on the roof of a nearby building.

Fox News contributor Nicole Parker reports on information she received about the shooting at the Turning Point USA event at Utah Valley University on 'The Story.'

The FBI has released video footage showing a suspect in the fatal shooting of Charlie Kirk jumping off a roof and fleeing the scene. The security service is offering a $100,000 reward for anyone with information.
