Crime: Idaho murders: What we don't know about the brutal slayings of 4 university students

University of Idaho victim's father says Xana Kernodle had 'bruises,' put up a fight against killer

  University of Idaho victim's father says Xana Kernodle had 'bruises,' put up a fight against killer University of Idaho murder victim Xana Kernodle's father said the 20-year-old had 'bruises' and was 'torn by the knife' while putting up an apparent fight with her attacker.Xana Kernodle, 20, was killed in the early morning hours of Nov. 13 — along with her boyfriend, Ethan Chapin, and two friends, Madison Mogen and Kaylee Goncalves — in a home on King Road in Moscow, Idaho, near the university. Police have not mentioned any suspects or a motive as of Thursday.

The small college town of Moscow is reeling after four University of Idaho students were savagely murdered more than one week ago – and a series of puzzling questions remain unanswered.

Ethan Chapin, 20, Xana Kernodle, 20, Madison Mogen, 21, and Kaylee Goncalves, 21, were stabbed to death Nov. 13 between 3 and 4 a.m. on the second and third floor of a rented house near campus and fraternity row.

Investigators, amateur online sleuths and the victims' families are desperately searching for clues – alongside the Moscow Police Department, Idaho State Police and the FBI.

Latah County Coroner Cathy Mabbutt said the victims were likely ambushed in their sleep with a large knife – and some of the slain students had defensive wounds, suggesting a violent struggle.

Officials have not identified any suspects or persons of interests in the killings or determined whether the attack was perpetrated by more than one assailant.

The coroner previously said the killer(s) likely used a large knife to stab each of the victims multiple times in the chest – but police have not recovered a murder weapon.

Retired NYPD Sgt. Joseph Giacalone said that the investigation is complicated by the most of the students leaving town for the holidays.

Idaho murders: police have 'cleared' phone calls victims made on the night of stabbings

  Idaho murders: police have 'cleared' phone calls victims made on the night of stabbings Police said Sunday that they have cleared multiple phone calls two victims of a Nov. 13 quadruple homicide near the University of Idaho campus made the night of the murders.Victims Kaylee Goncalves, 21, and Madison Mogen, 21, made "multiple" phone calls to a male subject just before they were stabbed to death while sleeping, but police have "cleared" the subject on the receiving end of those calls, Moscow Police Department Chief James Fry said during a Sunday press conference.

Mabbutt said there was no sign any of the victims had been sexually assaulted. But the nature of the crime suggested it was personal, said Morgan.

"This is passionate crime," he said. "You have an individual who was willing to get so close that he could feel the breath of his victim when he drove the knife into their chests."

He added that a crime can still be sexually motivated in the absence of a sexual assault.

On the second floor, the rooms are separated by a living room and kitchen area.

Half-empty Idaho campus full of fear, grief after killings .
BOISE, Idaho (AP) — In a normal year, University of Idaho students would be bustling between classes and the library, readying for the pre-finals cramming period known as “dead week.” On Wednesday, however, a little under half the students appeared to be gone, choosing to stay home and take classes online rather than return to the town where the killings of four classmates remain unsolved, said Blaine Eckles, the university's dean of students.On Wednesday, however, a little under half the students appeared to be gone, choosing to stay home and take classes online rather than return to the town where the killings of four classmates remain unsolved, said Blaine Eckles, the university's dean of students.
