The FBI has released images of a person of interest in the Charlie Kirk shooting, offering a $100,000 reward for information. The killer is still at-large 

Authorities say the shooter fired from a central building that houses the university's welcome center. Part of that building is just over 100 meters from the location where Charlie Kirk was speaking to an estimated crowd around 3,000.  A live stream of the video, with high-quality audio, captures the assassination. Many in the crowd duck, scream, and start to panic in the moments after the single shot is fired.

Police say a high-powered rifle has been found in nearby woods, as well as a "footwear impression... and a forearm imprint."
