Police believe they have found a haunting connection between the University of Idaho murders and the gruesome stabbing of a couple in Oregon.
Investigators said the killings shared characteristics of an earlier fatal knife attack on a sleeping couple in Salem.
Moscow Police Chief James Frye said officers were investigating links between the unsolved double stabbing of Travis and Jamilyn Juetten last August and the University of Idaho murders.
Travis and Jamilyn, like the student victims, were stabbed in the middle of the night with a long knife.
“We’re looking at every opportunity and there are other agencies that are reaching out to us with other cases and things we’re going to follow up on,” Frye said, confirming his team had the case on their radar.
“Actually, a tip came in about that case and I forwarded it,” Frye said.
The Salem couple was killed by a masked intruder as they slept at 3am.
Friends said Travis, 26, died trying to stop the crazed killer from attacking his 24-year-old wife.
Their family had offered a $50,000 reward for information leading to the killer’s murder.
As with the Idaho case, the killer struck while other people were home at the time, the New York Post reports.
The Juettens were cat sitters when the attack happened.
According to KOIN 6, the pair would fly to Hawaii the next day.
Idaho police say they still have no suspect in the murders of 21-year-old Kaylee Goncalves, 20-year-old Ethan Chapin, 20-year-old Xana Kernodle, and 21-year-old Madison Mogen.
But a case informant has now told Radar Online that the case can be solved with “biological waste”.
They said: “It is almost certain that biological waste will be found under fingernails [if a] battle took place … This will be crucial for the forensics.”
Investigators said some of the victims had defensive wounds after being attacked while they slept.
And the family of one victim, Xana Kernodle, has already said injuries to her body indicate she fought back to defend herself against her killer.
Her father Jeffrey told CBS5 in Arizona that the 20-year-old’s autopsy showed “bruises torn by the knife.”
Police said the victims were found on the second and third floors of the six-bedroom house, but on Sunday declined to say specifically which floor the individual victims were found on.
Since then, heartbreaking TikTok videos have surfaced showing the four University of Idaho students laughing together over the same house in which they were murdered.
Mystery continues to surround the case after two other roommates came to light who were in the house the night of the murders, but slept during the attack and woke up later that day.
