Why Idaho suspect Bryan Kohberger has been arrested - and reasons why a ... trends now

Suspected quadruple murdered Bryan Kohberger appears to be preparing to fight the allegations against him in court – with legal experts warning that the case is not a 'slam dunk'.

An unsealed arrest affidavit revealed a painstaking investigation by Moscow Police and the FBI to track down the 28-year-old criminal justice graduate student.

But despite evidence linking Kohberger to the crime scene, the other evidence has been described as 'circumstantial' by experts interested in the case.

He has been denied bail after two short court appearances in Moscow, Idaho, and is set to appear again for a preliminary hearing in June.

There are still several questions raised about the brutal slayings on November 13, which left an entire town terrified.

Court documents detail exactly how police linked Kohberger to the crime – but only his DNA on the knife sheath found at the scene appears to directly implicate that he was at the scene.

DailyMail.com looks at the reasons why police were able to obtain an arrest warrant for the suspected murderer – and why there are still questions being raised over if he will be convicted:  

5 REASONS WHY KOHBERGER WAS ARRESTED

1. DNA found on knife sheath

Officers called to the scene of the bloody grime on November 13 quickly discovered a K-Bar knife sheath next to the bodies of Maddie Mogen and Kaylee Goncalves.

The sheath is described as a tan leather knife sheath with a button snap and 'KA-BAR' and USMC' insignias.

Officers found trace DNA on the button of the sheath which was abandoned at the scene and managed to match it to Kohberger.

Unsealed court documents show the painstaking work done by officers, who matched the DNA found on the sheath to Kohberger's by comparing it to his father's DNA – which was a 99.9998 percent match.

FBI agents were tasked with tracking Kohberger so they could arrest him as soon as a warrant was issued as well as trying to get hold of an object to compare DNA to a sample found at the scene.

He was also seen cleaning the inside and outside of his car, with the source adding that he didn't 'miss an inch'.

Law enforcement saw him multiple times outside of his parent's $250,000 Pennsylvania home wearing surgical gloves.

Kohberger was also reportedly seen taking out the trash to his neighbour's bins at around 4am – with the contents being recovered by officers.

2. Car spotted at scene

A timeline issued by police indicates that Kohberger managed to break into the house and kill all four victims within a 15-minute period, before his car was seen speeding off in surveillance footage.

He even returned to the scene of the crime at 9am on November 13 - just hours after he allegedly committed the quadruple murders.

The car was spotted traveling towards the scene of the murders at 3.26am and was not displaying a front license plate.

Multiple cameras then caught the vehicle in the area of the property on King Road between 3:29am and finally at 4:20am.

Court documents describe how the car drives past the property three times, before coming back at 4:04am.

The car then 'unsuccessfully attempts to park or turn around in the road' in front of the house, before leaving and turning back into the direction of the property again.

It is next caught on camera leaving the area at a 'high rate of speed' at 4:20am. Police believe that the murders took place between 4 and 5am.

Kohberger's car is then tracked down to the Washington State University campus in Pullman, arriving back at his flat at 5:25am after the murders.

Officers reviewed Kohberger's drivers license information and photograph – which they say match the 'description of the mall seen inside the King Road residence' by surviving roommate Dylan Mortensen.

3. Phone signal 'vanishes'

Phone records show that Kohberger went close to the property just five hours after the murders were committed – with his phone being turned off during the time of the murders.

Police zeroed in on Kohberger by linking his white Hyundai Elantra to the scene and then using his phone number to track his movements.

They obtained the number from a previous incident where Kohberger was pulled over in August 2022 for a minor traffic violation and gave his details.

Court documents reveal how Kohberger turned his phone off in an attempt to cover his tracks before and after the murders.

On the night of the murders, Kohberger's phone pinged a cell tower close to his apartment in Pullman, Washington.

It then is seen leaving the area of his residence at 2:47am and traveling south through Pullman – which cops have confirmed lines up with the movements of his white Hyundai caught on camera.

His phone then stops reporting to the network, with FBI experts confirming that it is consistent with the phone being turned off, on airplane mode or in an area without phone coverage.

Court documents show that his phone is not active again until 4.48am, in the southbound lane of Highway 95 just south of Moscow.

Kohberger then travels towards Genesse, Uniontown and eventually back to Pullman between 4:50am and 5:26am.

The cell phone data then pings when he returns to his property, which is again caught on camera when the Elantra drives north on Stadium Drive at 5.27am.

His phone then left his apartment again at 9am and traveled towards Moscow, back towards the King Road residence and arrived between 9.12am and 9.21am.

Kohberger then returned home to his apartment in Pullman at 9.32am, with further analysis showing that Kohberger passed a coffee stand at 12.36pm after the murders.

He then went grocery shopping in Washington at 12.46pm, leaving at Albertson's grocery store at 1:04pm.

The suspected killer was in Johnson Idaho, between 5.32pm and 5.36pm – before appearing to be turned off again until 8.30pm.

Police say that his phone movements match that of his white Hyundai Elantra, which was caught on surveillance footage canvassing the scene before speeding away at high speed on the night of the murders.

His phone has remained off or not connected to the network since November 14.

4. Stalked the property at least 12 times prior to killings

Kohberger is accused of staking out the student home on 1122 King Road in Moscow on at least twelve occasions before the murders.

Officials have not revealed the exact dates that he canvassed the three-story property but confirmed that in August, he was pulled over just two minutes after leaving the area covered by the cell phone tower closest to the home.

A Latah County Sheriff's deputy pulled him over on August 21 at 11.37pm as part of a traffic stop – in which he provided his number.

Because of the series of traffic stops, officers were able to link both the car and the phone number to Kohberger – and look up each time his device pinged the tower closest to the property.

The documents say that the criminal justice graduate stalked the property in the late evening and early morning on each occasion – bar one.

Police made 'efforts to determine if Kohberger stalked any of the victims' before the killings and only detail that he was in the area of the property at least 12 times.

The affidavit added that they looked into if he 'conducted surveillance on the King Road Residents and was in contact with any of the victim's associates before or after the alleged offense.'

5. Messaging one of the victims before the murders

Law enforcement sources have revealed that two weeks before the killings of the four students, an account belonging to Kohberger sent a series of messages to one of the victims.

An Instagram account, believed to have been run by Kohberger, reached out to one of the female students but didn't get a response.

He reportedly 'slid into the DM's' of one of the girls, saying 'Hey, how are you' over and over again sources told PEOPLE.

It would be the first direct link between Kohberger and the victims, with court documents not detailing exactly how they came onto his radar.

Authorities remain tight-lipped about the details of the attack, and have not publicly commented on the relationship between Kohberger and the victims.

The account, which has since been deleted, reportedly followed
