OREM, UT – Authorities are still searching for the shooter who killed Charlie Kirk at an event at Utah Valley University, but have recovered a rifle believed to have been used to fire the single fatal shot.

A suspect was not identified, but authorities said in an update Sept. 11 that they recovered a high-powered rifle in the woods they believe was used in the shooting and learned new details about a suspect from video being analyzed.

Kirk, a 31-year-old conservative activist and close political ally of President Donald Trump, was speaking outside in a courtyard at the university on the afternoon of Sept. 10. The shooting, captured in graphic detail in video clips that rapidly spread around the internet, sparked fear and panic among the some 3,000 attendees, prompting the school to evacuate the campus and close down as authorities investigate. Some students fled while others barricaded themselves into classrooms, Utah Department of Public Safety Commissioner Beau Mason said.

The suspect "blended in well with a college institution" and appeared to be of college age, Mason said. The individual was seen on video jumping from a rooftop and running off campus.

"We do have good video footage of this individual. We are not going to release that at this time," Mason said, adding that investigators are using technology to help identify the suspect from the video.

"We are investing everything we have into this and we will catch this individual," he said.

The shooting, which officials have described as a "targeted attack" and "political assassination," drew swift condemnation from Republicans and Democrats. Trump, who ordered all U.S. flags to be flown at half-staff until sunset on Sunday, has vowed that his administration will "find each and every one of those who contributed to this atrocity."

Trump on search for Kirk's killer: 'We hope you get them'

President Donald Trump says he has been briefed on the search for Kirk's killer and plans to speak to the late conservative activist's family this afternoon.

"They have a virtual manhunt out there. So we'll see what happens. We hope you get them," Trump told reporters after a 9/11 observance ceremony at the Pentagon.

Trump confirmed Kirk's death on Sept. 10 on social media and said later, in a video on X, that he was filled with "grief and anger" over the fatal shooting at a college campus in Utah.

"What a great guy he was," Trump told reporters on Sept. 11. “You don’t replace a Charlie Kirk. He was unique."

New details about shooting suspect revealed

The shooting suspect was spotted on video footage entering campus at about 11:52 a.m. on Wednesday, minutes before Kirk's event was scheduled to begin. The shot was fired at about 12:20.

Investigators have video of the suspect entering the campus and going through stairwells and up to a rooftop location from which the shot was fired. After the shooting, investigators traced the suspect's movements off the roof before the individual fled off campus into a neighborhood. Authorities are looking for doorbell cameras and other security footage that may exist.

The rifle was located in a wooded area where the shooter fled, FBI Special Agent in Charge Robert Bohls said. Investigators also recovered an impression of the shooter's footwear, and other impressions left behind at and around the scene, Bohls said.

The FBI is looking for video and images of the incident and aftermath to help in the identification and capture of the suspect. It's not clear how far the shooter may thave gone, he said.

"No tip is too small," Bohls said.

2 people of interest cleared of being suspects

Two people were detained in the hours after the shooting, including one who was interrogated by law enforcement. Both were subsequently released and cleared of being suspects, Mason said.

Mason urged the public to cease harassment of the two people and have patience with the investigative process. The two previously detained people were facing scrutiny and threats, he said.

"There are no current ties to the shooting with either of these individuals," the Utah Department of Public Safety and the FBI said in a statement. "There is an ongoing investigation and manhunt for the shooter."

Video of Kirk's death spread quickly online. Think before you watch it.

Once you see the videos, you can't unsee them.

Graphic videos of Kirk's killing spread quickly online, appearing in people's social media feeds, often with little-to-no warning.

Getting confronted with gruesome, horrific imagery has, unfortunately, become an assumed risk when logging onto social media. Mental health and media experts, however, say the proliferation of violent videos online can have a deeply negative impact on our psyches − and that you don't have to view material like this in order to stay informed or have empathy for the victims.

What time was Charlie Kirk shot?

The shot rang out at about 12:20 p.m. local time on Wednesday, Sept. 10, authorities said. Kirk's event was scheduled to begin some 20 minutes earlier.

Kirk was taken to Timpanogos Regional Hospital in Orem just over 2 miles away from campus and was pronounced dead hours later, the Utah Department of Public Safety said in an update.

Who killed Charlie Kirk? What we know

Authorities have not named anyone believed to be involved in the shooting as of Thursday morning.

The shooter was "dressed in all dark clothing," Utah Commissioner of the Department of Public Safety Beau Mason said on Wednesday, noting that investigators were looking at security footage on campus for hints about the suspect.

The person is believed to have fired the shot from the roof of a building down to the student courtyard where the event was taking place, the department said in an update.

Six campus police officers and Kirk's traveling security team were working at the event, the department said.

Eyewitness describes fatal shooting: 'It was just terrible'

At a small makeshift memorial outside Timpanogos Regional Hospital, about a dozen mourners lit candles, held flags, and talked to each other in muffled voices. One of those paying his respects was Ammon Paxton, 19, who said he was about four people away from Kirk when the conservative activist was shot.

Paxton said he heard the shot go off, then saw the bullet hit Kirk. He said he watched him fall over and collapse.

"I can’t even describe how gruesome it was. It was just terrible," he admitted. "He was one of my biggest heroes and my greatest inspirations. I looked up to him a lot."

Paxton condemned the shooting, which he called an "assassination," and said he and other young conservatives will fight back against what he called violence from the Left, but within the traditional definition of "conservatism."

"I was pushed further right due to this event today, and I will not back down," he said.

But asked if he had a message for angry young conservatives who might be baited into retaliation for the shooting, Paxton said they should "stay focused on Jesus."

"This is not what Charlie Kirk would have wanted," Paxton urged. "He was a peacemaker."

Utah campus somber in wake of Charlie Kirk's killing: 'Doesn't feel real'

Panic and fear that broke out after Kirk was fatally gunned down during an outdoor event at Utah Valley University became shock and grief as students on campus began to process the attack.

Hours after Wednesday's shooting and a campus lockdown, a huge bouquet had been placed near a prominent university sign as police carrying machine guns patrolled the university, and the community hunkered down.

Lance Suaste, a university junior, said that she was near where Kirk was speaking when the shooting happened and that she saw the panicked crowd running.

"It doesn’t feel real so it’s very shocking," university junior Lance Suaste told USA TODAY. "Nothing like this happens in Utah." Read more here.

Charlie Kirk, a conservative activist known for pushing the envelope

Kirk, who was married and the father of two young children, had just returned to the United States from an overseas speaking tour in South Korea and Japan.

Known for his often-provocative discourse on topics ranging from race and gender to immigration and firearms regulation, Kirk often invited members of event crowds to debate him live.

At the moment he was shot, Kirk, a staunch advocate of the Constitution's Second Amendment right to bear arms, was being questioned by an audience member about gun violence, according to multiple videos of the event posted online.

Where is Utah Valley University located?

Utah Valley University is located in Orem, Utah, just outside of Provo and about 40 miles south of Salt Lake City. The university has over 45,000 students, according to its website.
