Prosecutors say a Mauser Model 98 rifle ties Tyler Robinson to Charlie Kirk while noting that ATF analysis did not conclusively match the bullet fragment recovered from Kirk’s body.In Provo prosecutors presented surveillance footage, DNA results, engraved bullets and video testimony from Lance Twiggs that they say place Robinson on campus and include texts and a handwritten note expressing remorse.The defense disputed the forensic certainty and investigative choices, the judge adjourned without a ruling and oral arguments are set before a probable-cause decision that could send Robinson to trial on aggravated murder charges carrying a possible death-penalty sentence.
