Utah prosecutors are turning up the heat on Tyler Robinson, the man accused of assassinating Charlie Kirk, arguing that the evidence against him easily meets the standard required to send the case to trial.Following the five-day preliminary hearing earlier this month, prosecutors on Tuesday filed the first of three written briefs ordered by Judge Tony Graf, urging him to send Robinson's case to trial and arguing the evidence overwhelmingly establishes probable cause on every charge."This is likely as straight-forward a bindover decision as this Court will ever see," prosecutors wrote. "After admitting to several friends, including his roommate and romantic partner, that he assassinated Charlie Kirk at Utah Valley University (UVU) on September 10, 2025, in front of approximately 3000 eyewitnesses, Defendant surrendered to law enforcement for that crime."The filing argues Robinson's alleged admissions are only part of the case.FRIEND OF CHARLIE KIRK LABELS COURTROOM EVIDENCE 'DEVASTATING' AFTER CHILLING SURVEILLANCE FOOTAGE SHOWN"These admissions, along with others, establish probable cause to support most of the elements of the charges," prosecutors wrote."DNA testing, surveillance video, and eyewitness testimony buttress those elements and demonstrate probable cause to support the remaining elements. The Court should bind Defendant for trial over on all counts," they continued.TYLER ROBINSON'S AND LANCE TWIGGS' DNA BOTH ALLEGEDLY FOUND ON KEY EVIDENCE IN CHARLIE KIRK'S ASSASSINATIONAccording to the filing, Robinson allegedly confessed to former roommate and romantic partner Lance Twiggs, writing, "I had the opportunity to take out Charlie Kirk, and I took it."Prosecutors say Robinson also admitted planning the assassination for "a bit over a week," discussed trying to retrieve the rifle after the shooting and later wrote, "I'm going to turn myself in willingly."CHARLIE KIRK JUDGE DENIES TYLER ROBINSON'S ATTEMPT TO HAVE POTENTIAL DEATH PENALTY REMOVEDThe 28-page memorandum repeatedly points to evidence introduced during the preliminary hearing, including surveillance video investigators say tracked Robinson across Utah Valley University before and after the shooting, DNA recovered from the suspected murder weapon, a fired cartridge casing, a towel and screwdriver, and eyewitness testimony placing the alleged gunman on the rooftop overlooking Kirk's event.FOLLOW US ON XProsecutors argue the evidence leaves little doubt that Robinson should be bound over for trial on all seven counts.CLICK HERE FOR MORE U.S. NEWSProsecutors also argue Robinson planned the assassination for more than a week, intentionally targeted Kirk and knowingly endangered numerous bystanders by firing a high-powered rifle into a crowd gathered to hear the conservative activist speak.
