♪ >> byron: good evening. thank you for joining us. we begin with new details

emerging about the horrifying murders on an idaho college campus that took the lives of four young people in their prime. a new book offers a possible timeline of the murders and who might have been the target of the killings. here's abc's kayna whitworth. >> reporter: a year and a half after the brutal killing of four college students, xana kernodle, boyfriend ethan chapin, madison logan, and katie gonzalez. families and friends still awaiting justice as the trial has yet to be set for bryan kohberger. >> i hope people understand how 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: on november 13th of 2022, a quadruple homicide rocked the quiet college town of moscow, idaho, and the nation. it made headlines everywhere. >> now to the investigation into the deaths of four college

students from the university of idaho. there is news tonight, chilling new images -- >> reporter: it took over social media with theories. >> this is what i think happened in the idaho murders. >> unless you've been living under a rock, i'm sure you've heard of the university of idaho murders. >> reporter: as the victims' families and friends waited nearly seven weeks for a suspect to be arrested -- >> the arrest of a 28-year-old man in pennsylvania in connection with the brutal murders of four university of idaho students -- >> reporter: now new reporting about the murders detailed in a new book by award-winning author howard bloom. you've come to the conclusion that based on your research, your interviews, you believe that bryan kohberger did it? >> i believe that bryan kohberger did it, but there are two parts to that question. the first part is, can he be convicted in a court of law? and i think that's a much higher mountain to climb. >> reporter: "when the night comes falling," based in part on

blum's early conversations with the police department, before a gag order shrouded the investigation into secrecy. >> i was able to reconstruct this night when everything seems to fall apart. >> reporter: it all began november 12th, 2022, a saturday night in college. friends headed to local bars and parties. kaylee gonsalves and madison logan, newly 21, went to the popular campus bar the corner club around 10:00 p.m. >> these two girls were just there for each other. >> reporter: steve goncalves is kaylee's heartbroken father. >> 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 a.m., and by 1:40, kaylee and were seen laughing and taking pictures as they ordered from a food truck in downtown moscow.

>> i could tell by her body language, she was definitely feeling pretty good. i wish i could have been there and given them a hug. >> reporter: 1:56 a.m., the pair arrived home. according to authorities, their roommate, xana kernodle, and her boyfriend, ethan chapin, both 20, were at a fraternity party earlier that same night but also returned to that hoff-campus home by about 1:45 a.m. hours later, all four were dead. the other two roommates were already home and allegedly sleeping. they were unharmed. little information has been released to the public, but blum's book claiming to fill in some of the gaps that night. in your reporting, you come to the conclusion that maddie was the target in this? >> the authorities in their mind are convinced that the suspect came in through the sliding door on the second floor of the house. right once you enter the kitchen area, there's a bedroom that --

where delia mortensen was in. the left-hand side, the right-hand side, was zena's bedroom. if he was just on a killing spree, it would have been natural, instinctive, to go to one of those doors. instead, he goes up this narrow staircase, and he turns directly into maddie's room. and i think maddie was his target. >> reporter: sources tell both blum and abc news that the two surviving roommates were using their phones to communicate during and after the murders. >> according to testimony that was made to the grand jury, the two girls were communicating. they were texting one another. not just after, but at one point, during. during the killings. >> reporter: sources close to kohberger's family telling blum, his father, michael, was on edge as he picked up bryan from school that winter. >> he's been reading the headlines, he knows that four students were killed just 12 miles from his son's house.

he knows what a troubled son he has. the moscow police issue a bolo, a stop order on a car, that is a white hyundai elantra. he realizes, my son drives a 201,500 day elantra. >> reporter: according to blum's sources, bryan's own sister approached their dad, voicing her suspicions about bryan. what was that conversation like? >> she's a family psychologist. and she knows her brother is -- has had problems. she goes to michael and she says, "dad," in effect, "we have a real problem. i'm starting to believe that bryan could be involved in these killings." and what does michael do? he can't confront it. he just turns around and walks away. >> reporter: shortly after, police arrested bryan kohberger on december 30th, 2022.

the kohberger family not commenting on the claims in blum's book. his former public defender in pennsylvania, lace son labar, saying, "i find it brazen that such an esteemed author would publish a book based on multiple players of speculation, assumptions, and presumptions while bryan kohberger, veiled in innocence, has yet to have his trial." while blum details kaylee's father's efforts, they have never spoken with mr. blum about the contents of his book and they call it "fiction, a version made up by him relying on sources that have no responsibility or duty to speak the truth." in may of last year at his arraignment, kohberger stood silent. >> there's no reason for you to stand silent.

you truly believe yourself to be not guilty, say it. if you want to take a plea, say it. standing silent doesn't stop the growings, doesn't move it forward. >> reporter: investigators claim dna evidence and surveillance footage plus cell phone records all link kohberger to the murders. but his attorney maintains he had no connection to the victims. kohberger has been held at the lake county jail in moscow, idaho, since early 2023 while his team builds his case, claiming he's innocent. >> when will a trial take place? you know, that's the question that the defense does not want to be answered. their strategy seems to be delay, delay, delay. there's a wisdom that lawyers often say. if you have the facts, go into the courtroom and pound them. if you don't have the facts, pound the table. well, bryan kohberger's defense is doing a lot of table-pounding. >> reporter: a hearing next week could finally set a date for bryan kohberger's trial to begin.

festival stage, security, and maintenance. >> the reason that recovery point and healing appalachia wants this to happen is to show people that you can have fun, you can live a successful life, you can do things like go to concerts and still remain sober. >> working this festival means a lot to me, because i never thought that i could have fun without doing drugs and drinking. >> reporter: last year, the stage rocked with the sounds of trey anastasio. >> i am in recovery from opiates myself. >> reporter: hand government mule fronted by former allman brothers band guitarist. >> it hits home especially hard because we've lost so many amazing artists over the years. >> reporter: between sets, our camera caught a chance encounter. >> i've seen what you got in you. you already know recovery dynamics. we always want to hire good people, man. >> reporter: dominic mckenzie
