Responding to criticism that his department does not have the resources to handle the investigation, Moscow Police Department Chief James Fry said on Tuesday that his officers have a total of 94 years of combined experience.

He also highlighted the department is being supported by the FBI and ISP.

“We are supported by highly trained and experienced personnel from the Idaho State Police and the FBI. Their continued resources and knowledge are vital to our success,” Mr Fry also said on Tuesday.

“Our investigative units work under a unified structure and have the autonomy to move forward and solve this case. Despite statements about my team, we remain focused on solving the murder of four students to seek justice for them, their families and to help our community heal.”

In a statement to The Independent on Friday, Xana Kernodle’s family said they’ve decided to start a memorial endowment in partnership with the University of Idaho to keep her legacy alive.

Kernodle, her roommates Kaylee Goncalves and Madison Mogen and her boyfriend Ethan Chapin were killed inside the young women’s off-campus rental home in Moscow on 13 November. A month on from the brutal stabbings, the killer remains at large.

“We are asking anyone who is willing and able to donate any amount they are comfortable with. Please know that no donation is too small,” the family said. “We sincerely thank you in advance from the bottom of our hearts.

“At the very least, we hope to create some good out of such a terrible and heartbreaking situation.”

The parents of murdered Idaho student Kaylee Goncalves have desperately begged for answers about their daughter’s killer as the police continue to hunt for suspects.

The 21-year-old was one of four University of Idaho students knifed to death at their off-campus home in the city of Moscow in the early hours of 13 November.

“We just want this person found so bad,” Kaylee’s mother, Kristi Goncalves, told ABC News last week. “Where are you? Who are you?”

Kaylee, her best friend Madison Mogen, roommate Xana Kernodle and Kernodle’s boyfriend Ethan Chapin were all stabbed to death inside the home.

“This person went in very methodical,” added Ms Goncalves said. “I think he really thought it out. I think he was quick, I think it was quiet. And he got in and he got out.”

With each piece of information revealed or theory debunked, dozens more questions emerge.

The Independent’s Sheila Flynn, Rachel Sharp and Andrea Blanco report on the murders that have rocked the small town of Moscow.

Kristi Goncalves, whose 21-year-old daughter Kaylee Goncalves was stabbed to death in her off-campus rental home in Moscow on 13 November, appeared on the Today Show on Thursday and spoke of her family being “left in the dark” as her daughter’s killer remains at large.

Asked if she thinks the case could go unsolved, Ms Goncalves said: “I mean, in all honesty, that is a possibility. There’s a lot of unsolved murders.

“It’s sleepless nights. It’s feeling sick to your stomach. It’s being left in the dark.”

Her comments came as tensions over a lack of developments continue to rise between investigators and the families and the public.

Andrew Ramsey, whose six-year-old sister’s 1996 killing made national headlines and remains unsolved to this day, theorised in an interview with Fox News that Moscow Police, the lead agency handling the quadruple stabbings, is “dealing with a violent psychopath who has no known relationship with the victim.”

Investigators have not divulged whether they believe the perpetrator in the 13 November slayings of Kaylee Goncalves, Madison Mogen, Xana Kernodle, and Ethan Chapin knew the victims or not. Nearly five weeks after the stabbings, no suspects have been identified.

“Moscow PD are in a near impossible position,” Mr Ramsey told Fox. “They simply don’t have the experience to run a complex homicide investigation.”

Mr Ramsey commended the small police department, which wasn’t faced with any murders for seven years before the November stabbings, for having requested immediate help from the FBI and Idaho State Police.

Kaylee’s mother Kristi Goncalves shared her anguish over the case in an interview with the Today Show on Thursday, more than a month after her daughter was stabbed to death alongside friends Madison Mogen, Xana Kernodle and Ethan Chapin at an off-campus home in Moscow, Idaho, on 13 November.

Ms Goncalves revealed that some of the most gruesome details the family knows about the case came from a conversation between her younger daughter, who is 17, and Latah County Coroner Cathy Mabbutt.

Ms Mabbutt had given that description to Kaylee’s little sister over the phone, Ms Goncalves said.

“[Ms Mabbutt] asked her: ‘Are you sure you want to know this?’ And my daughter, thinking that she did, for whatever reason, said ‘Yes,’” Ms Goncalves said. “And she proceeded to tell her.”

Police investigating the murder of four University of Idaho students scoured a 24-mile radius for surveillance footage from the night of the stabbings.

Moscow investigators travelled to the nearby towns of Troy and Kendrick for the footage that could help in the investigation into the slayings of Kaylee Goncalves, Madison Mogen, Xana Kernodle and Ethan Chapin, according to a Fox News Digital report.

Store owners in those towns said that authorities showed up at their doors asking for surveillance video from 12 November and 13 November. Several other stores in that area including a liquor store, a coffee shop, a gym and a gas station were visited by police, per Fox.

Two weeks ago, police asked for the public’s help in tracking down the occupant or occupants of a white Hyundai Elantra in connection to the case.

Investigators have yet to name a suspect in the stabbing deaths of four University of Idaho students who were found dead in a home near campus last month.

The killings have drawn worldwide attention, especially among true crime aficionados. That’s likely because so few facts are known about the case, said Julie Wiest, a sociology professor at West Chester University of Pennsylvania and an expert on extreme violence in media.

“Usually by now, there’s more facts that have been released by law enforcement, so I could see that ramping up the sort of digging and almost grasping at straws by people,” Wiest told the Associated Press.

“It’s not that typical, except in high-profile cold cases, where you might see people digging in that way.”

Despite more details becoming available in the two weeks since the murders took place, key pieces of what happened in the early morning hours of 13 November remain missing.

Police have revealed the victims’ last steps, yet the timeline becomes blurry as the second part of the night of the murders progresses.

The pair walked straight down Main Street to a red brick building that used to host the now-defunct Garden Lounge; a favourite food truck, Grub Wandering Kitchen - fondly called Grub Truck by its many local fans – often parks outside on Main Street.

Goncalves and Mogen ordered, laughed and chatted with friends as they got their pasta carbonara; according to police, they got a lift home from a “private party” and returned to King Road around 1.56am.

Kernodle and Chapin returned to King Road at around 1.45am. The young couple had gone to a party across the road at Sigma Chi.

The other two roommates at King Road – who have still not been named by authorities – had gotten home first, around 1am, and fallen asleep, according to police.

Mogen and Goncalves both made multiple calls to the same number around an hour after they got home.

Goncalves’ sister said the unanswered calls were placed to her ex-boyfriend, who’d dated her sister for years before they amicably split, still sharing a dog named Murphy. He has been ruled out as a suspect.

Authorities believe a killer or killers fatally stabbed Chapin, Kernodle, Goncalves and Mogen between 3am and 4am.

Their bodies weren’t found until nearly nine hours later, around noon on 13 November.
