Il Nuovo Postiglione - Hunt for shooter of Charlie Kirk enters third day in US

The gunman fired a single, fatal shot into Kirk -- a 31-year-old who rallied youth support for President Donald Trump -- during an appearance at a Utah university on Wednesday.

Despite hundreds of agents from across 20 law enforcement agencies working the case, investigators appealed for the public's help on Thursday and unveiled new images of a man they want to question.

"We cannot do our job without the public's help," Utah Governor Spencer Cox told reporters, adding they had received more than 7,000 leads.

The images released Thursday showed a man wearing Converse shoes, a black baseball cap, dark sunglasses and what appeared to be jeans, with a long-sleeved top emblazoned with a design that included an American flag.

Police say they believe the shooter fired a single bullet from a rooftop up to 200 yards (180 meters) away, hitting Kirk in the neck.

A video played at the press conference shows a figure running across a roof at the university, then jumping to the ground and making his way off campus towards some trees -- apparently the location where a high-powered bolt-action rifle was recovered.

Cox, the Utah governor, said his state "will pursue the death penalty" when the shooter is captured.

- Dark moment -

Reflecting the highly political nature of the killing, Kirk's coffin was transported to his home city of Phoenix on JD Vance's official plane.

Footage showed the vice president with his hands on the casket as it was carried to Air Force 2.

The right-wing mediasphere was in a state of heightened emotion Thursday, with Fox News contributors recounting the impact Kirk had on their lives.

Fox News host Jesse Watters said Wednesday the killing showed his side of the political spectrum was under attack.

"Whether we want to accept it or not, they are at war with us. And what are we going to do about it?" he asked his audience.

Trump urged supporters to respond peacefully, telling reporters that Kirk had been "an advocate of nonviolence."

"That's the way I'd like to see people respond," he said.

- 'Totally surreal' -

Students at Utah Valley University on Thursday described their shock, and their broader fears as political divisions deepen across the country.

Dave Sanchez told AFP witnessing the killing made him "sick to my stomach."

"We watch him all the time and so it really does feel like one of your own family members, your own brother's been killed," said Sanchez, 26.

In Orem Park, several hundred people wearing red MAGA caps and holding American flags attended a vigil on Thursday evening, where they prayed and held a moment of silence.

"It still feels insane that this happened," Jonathan Silva, 35, told AFP. "It's totally surreal."

Silva's wife Angelina, 27, told AFP about how the violent political polarization made the couple question their plans to have a child.

"It seems a little hopeless to try to start a family and raise children in a society where there's so much hatred and so much division," she said.

Kirk, whom supporters have hailed as a "martyr", co-founded Turning Point USA in 2012 to drive conservative viewpoints among young people, with his natural showmanship making him a go-to spokesman on television networks.

The father-of-two used his audiences on TikTok, Instagram and YouTube to build support for anti-immigration policies, outspoken Christianity and gun ownership, and to spread carefully edited clips of his interactions during debates at his many college events.

In July 2024, Trump survived an assassination attempt during his election campaign.
