A veteran law enforcement consultant told reporters that the hand movements made by two members of Charlie Kirk's private security detail in a video taken moments before the conservative activist and Turning Point USA founder was fatally shot in Utah were routine security signals rather than evidence of a conspiracy.

Footage circulating online shows two men who appeared to be part of Kirk's modest detail standing behind him as he addressed a crowd estimated at about 3,000 at Utah Valley University. One man adjusts his cap while holding a phone; another shifts his arms and scans the courtyard. Moments later, Kirk, 31, was struck in the neck by a single rifle round fired from a rooftop roughly 200 yards away and collapsed beneath a white "Prove Me Wrong" tent as supporters fled the scene.

Stan Kephart, a retired California police chief and longtime security consultant, told the Daily Mail that the gestures were deliberate hand signals but not unusual for protection teams. "I can tell you from experience — those were definitely hand signals. The way they were done was not casual. It was more than one signal," Kephart said. He added that, in his assessment, the movements looked like routine check-ins with colleagues or supervisors and did not, by themselves, indicate an imminent threat.

"If he wasn't okay, or if he had something to say, he would have reverted not to hand signals, but to his communication system," Kephart said, urging caution against drawing darker conclusions from the clip. Turning Point USA did not respond to requests for comment.

Authorities say the shooter appears to have slipped onto a campus roof shortly before Kirk's appearance, used a high-powered bolt-action rifle to fire a single shot, and fled into a nearby neighborhood within minutes. The FBI released grainy images of a person of interest on Thursday showing a black-clad individual wearing sunglasses and a cap bearing an image of a bald eagle flying across a U.S. flag. Law enforcement officers searched the Utah Valley University campus and surrounding areas but had not identified a suspect as of Thursday evening.

Investigators recovered a rifle along with palm prints and footprints in a wooded area near the campus, officials said. Utah Gov. Spencer Cox described the incident as "a political assassination," and federal authorities have said the FBI's inquiry will be exhaustive, including analysis of video from before, during and after the shooting.

Kephart, 85, said the apparent precision of the attack and the use of a distant, elevated firing position would prompt a thorough federal investigation. He noted that private security for a high-profile political figure differs substantially from protections afforded to elected officials. "There were only six campus police officers on duty. They are well-trained, but that's not enough for a 2,000-plus crowd," Kephart said. He said federal protective operations would typically include days of site preparation, rooftop sweeps, mapped areas of responsibility and specialized surveillance technology such as shot-spotter systems.

Kirk's appearance at the university was the first stop of what his team billed as the "American Comeback Tour." He founded Turning Point USA in 2012 and emerged as a prominent voice in conservative activism. The shooting comes amid a string of politically charged violent incidents in the United States in recent years; officials have pointed to attacks across the ideological spectrum as evidence of rising threats to public political life.

Within hours of the Utah shooting, social media was flooded with videos, photos and speculation. Conspiracy theories about the identities and actions of people near Kirk circulated online even as investigators warned that no verified evidence supports many of the claims. Law enforcement agencies urged the public to rely on official statements and updates rather than unverified social-media posts.

Federal agents and local police have appealed for tips and said they are reviewing large volumes of digital evidence, including mobile phone video recorded by attendees. Officials have emphasized that analysis of the footage and physical evidence is ongoing.

As the search for the shooter continued, Kephart said forensic and video analysis would be central to building a prosecutable case. "The Bureau's investigation will be a deep dive," he said. "They'll be looking at every frame, every piece of physical evidence." Authorities encouraged anyone with information or additional footage to contact the FBI or local law enforcement.

The investigation remains active, and law enforcement officials have declined to confirm additional details about leads or possible motives while the inquiry is underway. The release of the person-of-interest images reflects investigators' interest in identifying anyone seen on campus or nearby before the shot was fired.

Officials have not publicly tied the images to a named suspect. As investigators continue to piece together the timeline, Kephart and other security experts have reiterated that private events lacking federal protective resources pose different risks and require different mitigation strategies than those provided for many elected officials and major public figures.
