allegations of rape, arguing that all of the sexual encounters with his accusers were consensual. two of the alleged victims are pursuing a separate civil suit against the actor, saying after the court's decision they are resolved to continue their fight for justice. we turn now to the tragic murders of those four college students at the university of idaho. with no new leads, the parents of the victims are now voicing their frustration and the close-knit community, still on edge. weeks after the brutal killings. a murderer remaining at large. here's abc's kayna whitworth. >> reporter: a horrifying quadruple murder in this idyllic college town. >> you can't imagine sending your girl to college and then they come back in an urn. >> reporter: four university of idaho students stabbed to death in an off-campus house. >> there is no person on campus who isn't affected by this.

harder? >> yeah. >> you're emotional. >> yeah. >> you don't want something like this to happen on your watch. >> no. >> reporter: it all began on november 12th. a saturday night in college. friends headed to local bars and parties. kaylee gonzalves and maddie went to the corner club. >> it was a party setting, everybody socializing with each other. with kaylee, she seems like her usual, bubbly self. so nothing suspicious. >> reporter: the pair were lifelong best friends and college roommates. >> these two girls were just there for each other. >> reporter: steve is kaylee's heartbroken father. >> they went to dances together? >> yeah, just a good, wholesome friendship that you hope every child has. and you're grateful that they have that. >> reporter: investigators say the two young women left the

corner club around 1:30 in the morning. 1:40, kaylee and maddie were seen laughing and taking pictures as they ordered from a food truck in downtown moscow. >> i could tell just by her body language that she was -- she was definitely feeling pretty good. and i wish i could have been there and given them a hug. >> reporter: at 1:56 a.m., the pair arrived home. getting a ride from what steve described as a sorority designated driver service. according to authorities, their roommate, shanna, and her boyfriend, ethan, both 20, were at a fraternity party earlier that same night. but also returned to that off-campus home by 1:45 a.m. hours later, they were all dead. the other two roommates allegedly asleep on the lower floor of the house. they were unharmed. police not releasing their ide identities, saying they're not suspects and they've been very cooperative.

>> i hope people understand all these kids that were a part of this were doing everything right. they were going to be the type of people that you want to be your neighbor. >> reporter: officials maintain the murders likely happened between 3:00 and 4:00 a.m. and that all six people were likely asleep at the time of the attack. but the victims' bodies were not discovered for another eight hours. >> some of them had defensive wounds. so it looks like, you know, they may have woken up and tried to fight back. >> it was fast. and nobody suffered and nobody felt like -- like that kind of pain. i know my daughter would have called 911 if she was aware of what -- any kind of spooky, wild thing. or at least she would have called one of us. >> reporter: authorities say the surviving roommates called friends over first and that the initial 911 call was made around noon, about an unconscious person. multiple people were on the line

with dispatchers. despite the nature of the murders, city leaders initially giving a reassuring message. >> you believe that the students and residents of the city are safe right now? >> right, especially because, given the very focused nature of what went on there, no other apartments nearby were involved. >> reporter: but days later, with a murderer still on the loose, they were walking that back. >> we cannot say that there's no threat to the community. and as we have stated, please stay vigilant. >> reporter: throughout the investigation, the police sharing very little information about the case, despite having collected mountains of evidence. >> i maintain that we still believe this was a targeted attack. >> i think it's hard for people to just accept that. >> i understand that. we're painting a picture. and we're trying to see what -- pull the pieces into that

picture. that takes time. it's not something that happens quickly. >> reporter: more than two weeks later, police still have no suspect and no murder weapon, which they describe as a fixed-blade knife. >> i spoke with the general manager of a local home improvement store, and he said that police have been by asking whether they'd sold anyone a k-bar style 95, a ka bat-style knife. >> typically knives are used because it's highly personal. you physical have to touch them and you may have to fight them. far different from pulling out a gun and shooting them. >> reporter: authorities say there was no sign of forced entry. >> i think people think the local police do a good job, but they may also be, you know, quite inexperienced when it comes to dealing with a homicide investigation. >> i know this is a small department. i know it's a dedicated department. but do you believe you were prepared to handle something like this? >> so, we're trained. very well. we send officers to in-house

training, we send officers to training outside the area. then we bring in resources that we need. >> reporter: the fbi and state police immediately joining the effort. >> they can provide maybe insight to things they see at this particular scene. the way the people were killed. the positioning of the bodies. where were they stabbed? all of those things may tell you more information about the killer. >> reporter: in the absence of answers or justice, the community focusing on the lives lost. ethan chapin, the eldest of triplets, the first to be laid to rest last week. his grieving mother honoring his legacy at his memorial service. >> today we're here to honor the life and legacy of our son and brother, ethan chapin, one of the most incredible people you will ever know. . >> reporter: kaylee's father says she was cremated. but the family unwilling to hold her funeral yet because of fear
