The former roommate of the suspect accused in Charlie Kirk's murder will not have to testify in person during a preliminary hearing in the case, a Utah judge ruled on Monday. The decision denied a request from the defense team representing the suspect, Tyler Robinson, and argued any testimony's credibility could be challenged later if the case goes to trial.Judge Tony Graf made the ruling during a hearing Monday morning, saying the purpose of a preliminary hearing is to establish whether there is enough evidence to justify bringing the case to trial, not to determine whether someone is innocent or guilty.Graf also postponed a ruling until Friday on whether prosecutors could face sanctions for comments to the media about a bullet fragment recovered from the conservative activist's body. The defense team had asked Graf to block the death penalty in the case, claiming the prosecutors' comments could sway potential jurors regarding his guilt.Robinson, 23, has not yet entered a plea. He is charged with aggravated murder in the Sept. 10 killing of Kirk, a close ally of President Trump, who was shot in the neck while addressing a crowd of thousands at Utah Valley University. Prosecutors have said DNA consistent with Robinson's was found on the trigger of the rifle, the fired cartridge casing and two unfired cartridges. They have also said Robinson reportedly texted his roommate, who was also his romantic partner, that he targeted Kirk because he "had enough of his hatred."But Robinson's defense team said in court filings in May that a bullet fragment recovered during an autopsy could not be conclusively connected to the rifle found near the scene of the shooting, citing an analysis from the Bureau of Alcohol, Tobacco, Firearms and Explosives. The defense team asked the judge to delay the preliminary hearing, originally scheduled for May, so that they could review material, including the bullet analysis.Robinson's defense team asked the judge to block prosecutors from using recorded statements from the roommate in the preliminary hearing, set to begin on July 6. The roommate should be brought to testify in person, the defense attorneys said, so that Robinson can exercise his right to confront witnesses in person and challenge their credibility. But Graf denied that request, saying the time for challenging witnesses will come later.
