President Donald Trump urged supporters Thursday to respond peacefully to the killing of right-wing campaigner Charlie Kirk, as the murderer continued to evade a manhunt more than 24 hours after the shooting put an already divided US on edge.

Utah authorities have released more close-up images of a person of interest in the fatal shooting of Charlie Kirk, a Donald Trump ally, at Utah University. The FBI is offering a $100,000 reward for information leading to the suspect’s arrest. Kirk was shot while attending an event, and videos show a dark figure on a rooftop.

The officials rescued two women from the affected area, out of which one succumbed to her injuries during treatment.
