The FBI on Thursday released two photos of a person of interest in the shooting of conservative political activist Charlie Kirk .
The grainy photos show a person wearing a black long-sleeve shirt, dark pants, sunglasses and a hat.
"We are asking for the public's help identifying this person of interest in connection with the fatal shooting of Charlie Kirk at Utah Valley University," the FBI's Salt Lake City field office said in an X post with the photos.
The FBI said later Thursday that it is offering a reward of up to $100,000 for information that leads to the identification and arrest of those responsible.
The new information and reward offer came hours after law enforcement officials said they have recovered key evidence in Kirk's assassination at an event at Utah Valley Unive
