It's judgment day for Bryan Kohberger, the former aspiring criminologist who killed four University of Idaho students in a 4 a.m. home invasion ambush in November 2022.

The 30-year-old was studying for a Ph.D. at Washington State University in Pullman when he drove about 10 miles to the off-campus rental house at 1122 King Road, just across the state line, in Moscow, Idaho.

At a change of plea hearing July 2, he admitted to killing four young people inside: Madison Mogen, 21, Kaylee Goncalves, 21, Xana Kernodle, 20, and Ethan Chapin, 20. But he did not give a motive or explain anything other than admit his guilt.

Their families are expected to address him directly in court today with victim impact statements in a sentencing hearing expected to take all day.

Mogen and Goncalves, who were best friends, were killed in a third-floor bedroom. Kohberger's key mistake — the only publicly known physical evidence tying him to the crimes — was a Ka-Bar knife sheath he left under Mogen's body. Police found his DNA on the snap.

On the second floor, Kernodle was awake, having received a DoorDash delivery minutes earlier. Kohberger killed her, then turned his knife on her sleeping boyfriend, Chapin, who was spending the night.

A surviving roommate told police she heard crying and a man's voice say something to the effect of, "It's OK. I'm going to help." Then she saw a masked man with "bushy eyebrows" leave out the back door. For whatever reason, he didn't attack her.

The victims' families have been split over the plea deal, which required Kohberger to waive his right to appeal and to forfeit his right to seek a sentence reduction under Idaho law. Some of the families, but not all, are expected to deliver victim impact statements in a proceeding court officials predicted would run for the full day.

It remains unclear what, if anything, Kohberger will say.

While the plea deal specifically didn't require Kohberger to explain his actions at the July 2 hearing, Goncalves' father and many others, including President Trump, have said they hope he is required to give greater detail at sentencing.

BRYAN KOHBERGER PLEADS GUILTY TO IDAHO MURDERS

Chapin's parents and the mothers of Kernodle and Mogen have all voiced support for the plea deal, which will spare them from years of appeals and the trauma of a trial. 

In exchange for his guilty plea, Kohberger avoids the death penalty and is expected to receive the maximum punishment of four consecutive life prison sentences with no possibility of parole, plus another 10 years.

His sentencing begins Wednesday at 9 a.m. Mountain Time, 11 a.m. Eastern.

Trump border czar Tom Homan fired back Tuesday night at Hunter Biden for a recent profanity-laced rant against President Donald Trump's policies on illegal immigration.

"I don't really care what the former first drug addict thinks," Homan told Laura Ingraham on "The Ingraham Angle."  "I just thank God every morning I wake up we got President Trump in the Oval Office. And because of President Trump, in seven weeks we got the most secure border in this nation's history.

"And now we're arresting public safety threats and national security threats every day across this country," he continued. "We've already arrested three times the number of criminals that Biden did in the same timeframe."

BORDER CZAR TOM HOMAN'S MESSAGE TO ANTI-ICE PROTESTERS: 'YOU WANT SOME? COME GET SOME'

Biden recently sat down with "Channel 5" podcaster Andrew Callaghan for a wide-ranging discussion of his father's presidency, his drug use and other topics. 

During the interview, he slammed Trump as a "f------ thug" and compared his deportation agenda to Nazi Germany.

"There is a minority group that those in power, that came into power through democratically elected means, are going to target this minority group because they're stealing all the jobs," Biden said.

"And what we're going to do is we're going to send masked men to this marginalized group, and we are going to take them, put them on planes, put them on buses, put them on trains, and send them to a prison camp in a foreign country," he continued.

"What am I describing right then? Am I describing Germany? Or am I just describing the United States right now? Because I will tell you what. You think that the prison in El Salvador is not a f---ing concentration camp, you're out of your f---ing mind."

Biden infamously revealed to "CBS Sunday Morning" in 2021, that he would smoke "anything that even remotely resembled crack cocaine," including "more Parmesan cheese than anyone you know."

Salvadoran President Nayib Bukele also responded to Biden via a post on X, also referring to Biden's history of drug use. 

"Is Hunter Biden sniffing powdered milk?" Bukele asked, adding a clip from the interview.
