Bryan Kohberger case: Footprint found inside Idaho crime scene could help cops build case

Idaho murders recap: Suspect extradited, appears in court and more information on the crime

Within the span of a week, we finally learned the name of the alleged killer-- Bryan Kohberger. He was arrested at his parent's home in Pennsylvania and was extradited back to Idaho. He appeared before a judge to face four first-degree murder charges and a burglary charge. If convicted, he could get life in prison or the death penalty from just one murder charge.

MOSCOW, Idaho - The footprint found inside the Idaho home where a Ph.D. criminal justice student allegedly stabbed four University of Idaho undergrads to death could help police build their case beyond the initial probable cause affidavit, experts say.

However, its value may depend on what else detectives found with a series of search warrants served following the arrest of Bryan Kohberger, 28, more than 2,500 miles from the crime scene.

In a probable cause affidavit released Thursday morning, investigators revealed that a shoe print found at the crime scene had a sole pattern that resembled that of a Vans sneaker.

Kohberger, the Pennsylvania man accused in the quadruple murder, was seen wearing Vans-style shoes as authorities walked him into a Monroe County courthouse last week – but those cannot be the same shoes that left the footprint, experts tell Fox News Digital.

"They could be the prison shoes that they gave him, the slip-ons, because they don't want you taking off the laces and hanging yourself," said Joseph Giacalone, a retired NYPD sergeant and adjunct professor at John Jay College of Criminal Justice.

If police have recovered the shoes that left the print, they would be in evidence, he added. It was not immediately clear whether police had found a matching shoe, however.

Kohberger is accused of prowling around the home at least 12 times before Nov. 13, when police allege he went inside and ambushed Maddie Mogen, 21, Kaylee Goncalves, 21, Xana Kernodle, 20 and Ethan Chapin, 20.

Judge Megan Marshall issued a gag order on the case last week, barring investigators and attorneys for both sides from making public comment on many aspects of the case.

Chilling details emerge as Kohberger faces Idaho judge

The man accused of killing four University of Idaho students is facing a judge for the first time.

Additionally, if police do not have the sneaker, the size of the shoe that left the print could also be important, Giacalone noted.

"It still doesn't answer the question of how he knew these girls," he said. "That's the big mystery still."

According to Shanon Gray, the attorney for Goncalves' parents, "no one" knew about Kohberger before the slayings. Any links the families uncover will be forwarded to Moscow police, he said.

Paul Mauro, a former NYPD inspector and currently a lawyer, said the print is likely important because of how police found it – by using chemicals that detect the presence of blood.

"First of all, they got the footprint, but also it probably helped them develop his path through the house, because by using the technology that they did, it sounds like what they picked up was a blood footprint," he told Fox News Digital. "He stepped in blood of some sort and left that impression, and apparently it's very vague…very faint, so they had to use this technology – which means he might've wiped it up."

It will also help police track the suspect's movements throughout the house, he said.

A surviving housemate, identified in the affidavit of Moscow Police Cpl. Brett Payne as DM, told police she saw a masked man with "bushy eyebrows" walk by her on his way out the back door after hearing a series of alarming sounds.

She told detectives she thought she heard Goncalves "say something to the effect of ‘there’s someone here,'" according to Payne. She looked out her door, saw nothing, and then told police she thought she heard crying from Kernodle's room.

"DM then said she heard a male voice say something to the effect of 'it's ok, I'm going to help you,'" the affidavit continues.

She opened the door again and saw "a figure clad in black clothing and a mask that covered the person's mouth and nose walking towards her."

She told investigators she saw a male, athletic but not muscular, about 5 feet, 10 inches tall, with "busy eyebrows," Payne wrote in the affidavit.

"The male walked past DM as she stood in a ‘frozen shock phase,’" he continued. "The male walked towards the back sliding glass door."

Police said they believe the suspect left at that time.

The footprint, according to the affidavit, was "consistent with DM's statement regarding the suspect's path of travel."

These details can help investigators determine the order in which the victims were attacked.

Kohberger faces four counts of first-degree murder and a felony burglary charge for allegedly entering the house with the intent to kill.
