“President Donald Trump on Friday said that a suspect in the Charlie Kirk assassination had been captured, ending a tense two-day manhunt after the FBI had circulated video and images of the suspect but withheld his name.
Jason Pack, a retired FBI supervisory special agent, told Fox News Digital that the strategy was intentional — designed to protect both the investigation and public safety — and it mirrored the 2013 Boston Marathon bombing probe.
