Newly surfaced images reveal crucial evidence left by Bryan Kohberger, the perpetrator behind the chilling murders of four University of Idaho students. These pictures, recently released, provide a stark look at the trail he left on that fateful night.

Among the evidence are size 13 footprints leading from the back door into the snow of an off-campus house in Moscow, Idaho. Additionally, a knife sheath left behind offers a vivid account of Kohberger’s actions during the early hours of November 13, 2022.

These images, part of a substantial 3,000-file release from the Idaho State Police, briefly appeared online before being quickly removed. The Daily Mail managed to access and report on these haunting visuals before their swift removal.

Central to the evidence was a 13-inch tan leather knife sheath, fitting a KA-BAR-style combat knife, which was identified as the murder weapon used in the brutal killings of Xana Kernodle, Kaylee Goncalves, Madison Mogen, and Ethan Chapin.

This sheath was discovered on a bed in Madison Mogen’s room, amidst sheets soaked in blood, serving as a key piece in the investigation.

Forensic analysts used traces of DNA samples from the sheath to identify Kohberger as the killer.

Kohberger had purchased a set of knives months before the murders, and investigators traced it back to him.

Officials initially believed the killer left the sheath behind in an attempt to mislead the investigation, but later said Kohberger had left it behind in a panic during the frantic slayings.

During the investigation, officers found footprints in the snow leading away from the home.

The large, size 13 shoe print was also discovered inside the bloodied crime scene after detectives used a chemical agent on the floor, according to the outlet.

A Nike shoe seized by police at Kohberger’s home after his arrest matched the size of the print at the Idaho house.

Kohberger, who pleaded guilty to the quadruple murders in July, carried out the massacre in minutes, launching the attack at around 4 a.m.

He is believed to have snuck in from a sliding side door before making his way upstairs to Mogen’s bedroom, where she was sleeping with Gonclaves and hacked the 21-year-olds to death, leaving the DNA-covered sheath.

Kohberger then encountered Kernodle, 20, who had grabbed a food delivery and was returning to her room on the second floor.

Here’s the latest coverage on Bryan Kohberger:

The masked killer butchered Kernodle before making his way to her bedroom, where he found 20-year-old Chapin sleeping and murdered him.

The graphic images painted the closest images of the gruesome scene since the killings.

Idaho police “temporarily” removed the short-lived photo dump of the horrifying blood scene because of “privacy concerns” to allow for a further review of the files before reposting them.

“Following adjudication of the criminal case, the Idaho State Police received a large volume of public records requests seeking the photographs,” a spokesperson for the department said in a statement.

“In making the redactions, the Idaho State Police also chose to follow Judge Marshall’s permanent injunction, which required the City of Moscow to redact areas of the photographs depicting ‘any portion of the bodies of the decedents or the blood immediately surrounding them,’” the statement continued.

”After questions were raised, the records were temporarily removed for further review to ensure the appropriate balance between privacy concerns and public transparency was struck.”

Kohberger, who was a graduate student at the nearby Washington State University in Pullman, Washington, was handed four life sentences without the possibility of parole at the Idaho Maximum Security Institution.

His controversial plea deal saved him from being sentenced to death.
