PROVO, Utah — Lawyers for the man accused of killing conservative activist Charlie Kirk planned to call a final witness Friday as they try to raise doubts about the prosecution’s case before it can go to trial.

A Utah judge is deciding whether prosecutors have enough evidence to put Tyler Robinson on trial on a charge of aggravated murder. Kirk, 31, was killed as he spoke to a crowd of thousands at Utah Valley University on Sept. 10.

One of Robinson’s attorneys, Michael Burt, tried to inject uncertainty into the case Thursday by challenging the reliability of ballistics tests on a bullet fragment recovered from Kirk’s body.

Authorities sought to tie the fragment to the suspected murder weapon, but the results were inconclusive.

“Saying anything but inconclusive was inappropriate,” said Samantha Karner with the Bureau of Alcohol, Tobacco, Firearms and Explosives.

Earlier in the week, Robinson’s team questioned the reliability of DNA evidence that investigators said linked Robinson to the scene. Experts say the science behind DNA testing is sound.

Robinson has not entered a plea. He turned himself in a day after the fatal shooting of Kirk, a close ally of President Trump credited with helping galvanize young voters for the Republican in the 2024 election.

At the request of Kirk’s family, State District Judge Tony Graf said he would allow to be shown inside the courtroom an altered version of campus surveillance video that prosecutors said shows Robinson crawling out to a rooftop “sniper’s perch” before shooting Kirk.

The unaltered video was previously shown. The altered version includes footage that zooms in on a figure that prosecutors said was Robinson and red marks that were added to the video.

The weeklong preliminary hearing ends Friday, but a decision won’t come until after Sept. 1, when Graf scheduled oral arguments in the matter.

Prosecutors on Thursday aired portions of a recorded interview with Robinson’s roommate, Lance Twiggs. The day after Kirk was shot in the neck, Robinson allegedly told Twiggs “he wishes he hadn’t done it,” a recording played in court revealed.

Later that same day — and only about an hour before turning himself in — Robinson posted “it was me at UVU yesterday,” in a chat room on the Discord social media platform, according to investigators and messages shown by prosecutors.

Defense attorneys unsuccessfully fought the public release of the statements from Twiggs and the chat room messages. They argued prosecutors would characterize the material as a confession, undermining Robinson’s right to a fair trial.

Prosecutors contend the shooting endangered others at Kirk’s campus event — an aggravating circumstance that could make the crime punishable by death under Utah law. Robinson also faces possible sentence enhancements based on claims by prosecutors that he targeted Kirk because of his political views.

Twiggs said in the April interview with prosecutors and investigators that Robinson sometimes talked about politics, including Trump. But Twiggs said he never heard Robinson talk about Kirk before the shooting. The defendant also did not talk much about gender issues or LGBTQ rights, Twiggs said.

The weeklong preliminary hearing has attracted intense media coverage and spectators who have angled for one of the 14 seats in the courtroom that are reserved for the public.

People have lined up early — sometimes sleeping there overnight — in hopes of getting in.

Detroit Lions cornerback Terrion Arnold has been arrested in connection to an alleged armed attack on a group of men in Tampa, Fla., in February. He faces eight felony charges of kidnapping and robbery that could keep him in prison for life if convicted.

Investigators believe Arnold was the “primary conspirator” in an alleged plot that left three young men with “visible injuries from being battered, held at gunpoint, and pistol-whipped before their personal property was stolen and they were ordered to leave,” the Tampa Police Department said Wednesday in a news release.

Six other suspects previously were arrested. Two women already pleaded guilty and agreed to help authorities prosecute Arnold, police said.

The second-year player turned himself in Wednesday night and was held in a Hillsborough County jail without bond before his arraignment hearing Thursday afternoon.

Arnold appeared remotely during the brief hearing, where he was charged with three counts of robbery with a firearm or deadly weapon for less than $750 and three counts of kidnapping to harm or terrorize, all of which are first-degree felonies. He was also charged with two second-degree felonies for conspiring to commit those crimes.

“He’s absolutely denying these allegations,” defense attorney R. Timothy Jansen said during Hillsborough County court proceedings.

Arnold will be held without bond until a pretrial detention hearing Monday, where the Hillsborough County state attorney’s office will argue for him to remain behind bars until trial.

According to Tampa police, several items belonging to Arnold and others were stolen Feb. 1 from an Airbnb rental property in Largo. They reported to Largo police that the items were worth more than $250,000.

The alleged incident that led to Arnold’s arrest occurred early Feb. 4. It was plotted, Tampa police said, because Arnold suspected that two of the three men were responsible for stealing the items. Investigators later determined those men were not involved, police said.

Police said the victims were lured to an apartment, where they were held at gunpoint and hit by suspects who were streaming the alleged attack to Arnold, who is accused of helping coordinate the plot and giving orders to the alleged attackers on a group chat during the incident. He later arrived at the apartment and drove some of the suspects away, police said.

“Fame doesn’t get you out of criminal charges or our pursuit of justice and holding criminals accountable,” Tampa police chief Lee Bercaw said in a statement posted to X. “Our victims now have some closure thanks to the great work of our detectives and our strong partnership with State Attorney Suzy Lopez.”

The head of the management agency that represents Arnold said in a statement that the former first-round draft pick “categorically denies any involvement in the matters unlying the allegations made against him and maintains his innocence.”

“There is no credible evidence linking Mr. Arnold to these allegations,” EAG Sports Management CEO Denise White said. “Instead, the government appears to be relying on testimony from multiple convicted felons who have admitted their own involvement and may have substantial incentives to shift blame in an effort to lessen their sentences.”

Arnold has played in 24 games for the Lions. He had 31 tackles and an interception last season before going on injured reserve with a shoulder injury on Dec. 1.

The Lions said they are aware of Arnold’s situation but have no further comment.
