The grieving families of four University of Idaho college students savagely murdered in 2022 – and, indeed, most of America – were shocked when it was reported Monday that accused killer, Bryan Kohberger, had accepted a plea deal to live out the rest of his life in prison.

Two days later, the emotionless killer appeared in a Boise, Idaho, courtroom where he verbally admitted his guilt on all counts. 

But beyond the justifiable outrage over the state prosecutor’s deeply cynical, yet pragmatic decision to put an accused murderer behind bars, many were left wondering: why now?

I, however, was not particularly surprised.

I began reporting on this case in the days immediately after the killings in Moscow, Idaho, spending weeks in that tiny, traumatized college town, crossing America to the small Pennsylvania lake community where Kohberger was born and raised and sitting in court as state prosecutors battled Kohberger’s savvy and determined court-appointed defense team.

It became apparent to me early on that Kohberger’s lawyers understood that the evidence against their client was convincing, even overwhelming.

There was no getting around the fact that a touch of Kohberger’s DNA was recovered from a knife sheath found on the bed of one of the murder victims.

It also would have been near impossible for them to explain why his car was near the house where the murders occurred at the approximate time of the killings and why he had no alibi on that freezing cold evening.

As I reported for the Daily Mail in April, Kohberger’s attorneys had been lobbying him to accept a plea deal taking the threat of execution by an Idaho fire squad (an antiquated method of capital punishment brought back into practice for Kohberger’s benefit) off the table. 

But, as a source close to the Kohberger family told me then, it was his mother Maryann, who repeatedly encouraged him to plead not guilty, frustrating the defense team’s strategy.

The mother’s apparent motivation is still unclear. Whether she was driven by a desire to protect her family reputation or a delusional refusal to accept reality, my source said she stood in a way of a bargain with prosecutions.

In fact, the Kohberger family was allegedly so resistant to a deal that Bryan’s lawyers argued in court that he had autism spectrum disorder (ASD) and that executing someone with the condition would constitute cruel and unusual punishment.

That was a ruse – I believe.

I suspect the defense’s true objective was to establish Kohberger’s alleged autism so that they could argue the disorder made him incapable of making reasonable decisions. And therefore, despite his reluctance, they would ask the court to accept his guilty plea – regardless of his consent – with the hope that in return the state will forgo the death penalty and accept a life sentence.

But now, my source tells me it was only in past few days that Bryan Kohberger’s resistance to a deal was broken.

Defense lawyers allegedly went back to Kohberger recently and warned him that if he goes to trial, his mother, father Michael and possibly even one of his two sisters would be called to testify.

A recent Dateline investigation, of which I took part, revealed that there are records of a phone call that Kohberger made to a cellphone registered to his father at 6am on the morning after the murders.

It is possible that Kohberger spoke to his mother in that conversation and Kohberger was warned, I’m told, that the state will likely grill her over what may have been said.

The defense team then assured Kohberger, my source said, that prosecutor would also undoubtedly question his father over the cross-county road trip they took together in December, after Michael drove from Pennsylvania to pick up Bryan and take him back home in Pennsylvania for the Christmas holidays.

By this time, there was a nationwide search for a killer. And while driving in Bryan’s Hyundai Elantra, the Kohbergers were stopped twice by police but ultimately allowed to drive on.

I was told that Bryan seemed distraught during the drive and confided in his father during that trip that he was in trouble at his job as a teaching assistant in the criminal justice department at Washington State University.

His father was quite possibly putting two and two together – and concluding that his son was running from something terrible.

Finally, I’ve previously reported that one of Kohberger’s sisters had confronted her father over her suspicions after she found her brother cleaning out his car and bizarrely sorting his garbage into different garbage bins across their neighborhood when he was home in December.

Some have speculated that Kohberger may have done that to hide trace DNA that might be left on his refuse from investigators seeking to link him to the killings.

All of this would be explored by prosecutors at trial and a source close to the family says that influenced Bryan’s decision to accept the deal.

Of course, there’s no way of my knowing how prominent that was in his thoughts. The defense also recently suffered a series of losses in court.

Judge Steven Hippler threw out the Kohberger team’s so-called ‘alternate perpetrator’ defense theory which suggest that four other people were involved in the killing. Hippler also rejected the defense’s attempt to claim that Kohberger didn’t need to establish an alibi because he was out driving by himself in the early morning hours before the murders.

So, what finally pushed Bryan Kohberger to accept a plea deal – condemning himself to life in prison?

It may be a combination of many factors – from his failing courtroom hopes to pressure from family.
