MOSCOW, IDAHO: Bryan Kohberger, the suspect in the murder of four University of Idaho students, may claim during his trial that the home where the victims were discovered was a "party house" to explain why his DNA was found at the scene, reported the Daily Mail.

Federal agents went back to the off-campus home where Kaylee Goncalves, 21, Maddie Mogen, 21, Xana Kernodle, 20, and Ethan Chapin, 20, were stabbed to death on November 13 to collect more evidence and take precise measurements to make a 3D model of the rooms for trial.

The former criminology PhD student is presently being held at Latah County Jail, awaiting the trial day. A documentary on the case, titled 'The Case Against Bryan Kohberger' is set to air on Court TV on November 12.

What did the documentary reveal about Bryan Kohberger's probable defense?

Criminal Defense Attorney Jack Rice says in the documentary that Kohberger's defense team could claim the scene of the crime to be a wild party house frequented by many.

In a clip obtained by the New York Post, Rice is heard saying, "One of the most important parts of this case is that DNA, and what we know is that this is a party house. We know that there are hundreds of kids in this house – it could have even included him."

"And the thing is, if he was in this house, are you suggesting that these four know everybody who's been there? I doubt that. All of sudden, you might have a completely different trial."

Kohberger’s DNA was found on a knife sheath that was present along with the dead bodies.

The defense had stated that they would be contesting the notion that Kohberger's DNA was left at the scene on the knife sheath. The DNA from three unidentified men was also reportedly found at the scene of the crime.

The claim of lots of people being present at the scene has been verified by neighbor Jeremy Reagan, who added that the parties had slowed down just before the time of the murders.

"They did have more stuff going on there, but they were definitely nowhere near as loud, as crazy," he said.

Bryan Kohberger may have an alibi for murders

An alibi has not yet been presented by Kohberger's legal team, but they have certainly hinted at one.

Anne Taylor, Kohberger's attorney, reportedly said in July, "Evidence corroborating Mr. Kohberger being at a location other than the King Road address will be disclosed pursuant to discovery and evidentiary rules."
