Parents of Idaho murder victim Kaylee Goncalves 'hope' she snatched knife ... trends now Kaylee Goncalves' parents say they take some comfort in the hope that their daughter's will to fight her killer was possibly what helped lead police to a suspect. Kaylee, 21, and her friend Maddie Mogen, were among four University of Idaho students stabbed to death at their home in Moscow, Idaho on November 13. A sheath that fit the KA-BAR knife believed used in the brutal slayings, was found beside their bodies, according to an affidavit released last week. DNA found on the sheath linked Bryan Kohberger, 38, to the crime scene and he was arrested after more than a month following the murders. Steve and Kristi Goncalves told Dateline NBC in a recent interview that the new details that seemed to paint a clearer picture of their daughter's final moments, gave them hope that through the struggle, she played some hand in solving her own murder by snatching the all-important sheath from her assailant. On Thursday, Kohberger appeared briefly in court where a preliminary hearing was set for June 26. Dateline NBC will air an all-new two-hour special this Friday at 9 ET/8pm CT on the latest in the investigation into the murders of University of Idaho students Kaylee Goncalves, Madison Mogen, Xana Kernodle, and Ethan Chapin. Kaylee Goncalves' parents say they take some comfort in the hope that their daughter's will to put up a fight against her killer was possibly what helped lead police to the arrest of a suspect Goncalves was found stabbed to death on November 13, along with her roommates Maddie Mogen, 21, top left, Xana Kernodle, 20, and her boyfriend Ethan Chapin, 20 Kristi Goncalves told Dateline's Keith Morrison that when she read the new details, she felt that her daughter did everything she could to fight back. 'I just... I just said, "Can you believe that?" And I said, "I hope thta maybe a struggle, she pulled it off him, in the struggle or whatever...' Kaylee's father Steve was teary eyed as he interjected: 'Yeah, it's a checkmate type moment. And our girls were a part of it.' The heartbroken parents who have been outspoken throughout the investigation, made a point of driving the 100 miles from their home to sit in court behind the man they believed killed their daughter. Kristi Goncalves told Morrison what it was like to sit in court and watch the accused killer. 'He looked scared, as he should be,' she said. If he is indeed the person, I feel that no mercy should be given to him.' Kristi Goncalves told Morrison what it was like to sit in court and watch the accused killer Kaylee's father Steve was teary eyed as he interjected: 'Yeah, it's a checkmate type moment. And our girls were a part of it' DNA found on the sheath linked Bryan Kohberger, 38, to the crime scene and he was arrested after more than a month following the murders The 28-year-old Washington State University graduate student charged in the grisly murders waived his right to a speedy trial and was held without bail. As he took his seat, scratches along the left side of his chin were clearly visible. It's unclear how he sustained the scratches. A deputy from the Latah County Jail told DailyMail.com that the cuts were 'accidental', and that Kohberger inflicted them on himself. He requested the gap in court proceedings - waiving his right to a timely hearing - to allow his attorneys more time to learn more about prosecutors' case against him. But he will return to court in Moscow on June 26 - six months from now - for a preliminary hearing. Accused Idaho killer Bryan Kohberger appeared in court today with a scratched face as he waived his right to a speedy trial The cuts extended up Kohberger's jaw-line. It remains unclear how he sustained them Kohberger's attorneys previously said he denied the killings, but he has not yet entered a plea. So far, Kohberger has only appeared before judges in Idaho's magistrate court division. If the case progresses to trial - which it is expected to - it will be moved to the district division, which is reserved for more serious offenses. The hearing in June will determine whether there is enough evidence for the case to proceed to the division court. Once it has, Kohberger will be asked to enter a plea. The parents of Idaho murder victim Kaylee Goncalves have said they support the death penalty for their daughter's alleged killer – but that they 'will forgive him'. On Friday's Dateline special, Morrison also speaks with friends and family members of the victims, as well as former acquaintances and classmates of Kohberger. Martha, a University of Idaho student who was friends with Ethan and Xana, tells Morrison that one of the 'toughest' things during the investigation has been dealing with internet sleuths on social media. She explained, 'It was odd because you'd be with people that you're literally actively grieving with and then you'd open Facebook or open TikTok and then it would be how the person sitting next to you is the one that did it.' Martha: One of the things that made it the toughest, was the TikTok sleuths. Keith: The TikTok sleuths. Martha: The independent TikTok sleuths and the people who made out the people that I love and know into monsters online. There was some really awful things written on the internet. Keith: Got a real life lesson on how cruel the internet can be. Martha: yeah. And it definitely - it went through all parts of our campus. Every digital footprint, every Venmo transaction, everything. Morrison: Any of your friends in particular get hurt or hit by this stuff? Martha: Yeah. And, you know, it was odd because you'd be with people that you're literally, like, actively grieving with and then you'd, like, open Facebook or you'd open TikTok and then it would be why the person sitting next to you is the one that did it A law enforcement source claims that the sheath found matches a 7-inch knife sold by KA-BAR - a manufacturer of hunting weapons The documents describe a tan, leather knife sheath with a button snap and 'KA-BAR' and USMC' insignias being found at the scene Kohberger's former DeSales University classmate Madison tells Dateline that during class, she 'would always catch him staring' at her and her friends. She also noted that he seemed to enjoy letting the class know he knew the answers, saying, 'He definitely took it upon himself to answer the question, but yet then give every single detail that he possibly could to help further his point. It was always like, 'Oh, Bryan's answering this question. This is going to take up the whole entire class.' Whenever he raised his hand he definitely took it upon himself to answer the question but yet then give every single detail that he possibly could to help further his point. It was always, like, 'Oh, Bryan's answering this question. This is gonna take up the whole entire class.' But there was something else that just didn't sit well with her. 'He would stare at us, whenever me and my friends would kind of, like, look over to the side, I would always catch him staring at us.' Friday's episode of Dateline, Killings in a College Town, will also feature a comprehensive look at the case, including expert analysis from former FBI agents and detectives. Dateline NBC will air an all-new two-hour special this Friday at 9 ET/8pm CT. All rights reserved for this news site (dailymail) and under his responsibility
