Among the many tips investigators in Idaho are sorting through on Thanksgiving Day is an unsolved stabbing attack from over year ago. 

Moscow Police Department Chief James Fry, whose department is leading the investigation into the murders of four University of Idaho students, said during a press conference on Wednesday that investigators received a tip about another stabbing last year in Salem, Oregon. 

In the Oregon case, Travis and Jamilyn Juetten were awakened from their sleep around 3:00 a.m. on Aug. 13, 2021, to an unknown assailant attacking them with a knife. Travis fought off the attacker, but was pronounced dead at the scene. 

Jamilyn suffered 19 stab wounds and other injuries, but was transported to a hospital and survived. Police do not have a suspect in that attack.

A reporter asked Chief Fry on Wednesday if investigators are looking into any possible connection between the quadruple homicide in Idaho and the Salem attack, noting that both cases involve an unknown assailant breaking into a home around 3:00 a.m. and attacking sleeping victims with a knife. 

"We're looking at every avenue and we have other agencies reaching out to us with other cases, stuff that we are going to follow up on," Fry answered, noting that he was aware of the Oregon case and had received a tip about it. No official connection has been drawn between the two cases.

In June 2022, ten months after Travis Juetten was murdered, his family offered a $50,000 reward for information leading to the arrest and conviction of his killer. 

A detective from the Marion County Sheriff's Office in Oregon assigned to the 2021 investigation did not respond to questions on Wednesday evening.

All four victims were stabbed multiple times and some of them had defensive wounds, a medical examiner determined. 

Police have not identified a suspect and do not have a murder weapon, but are looking for a "fixed-blade knife."
