Kaylee Goncalves’ sister, Alivea Stevenson, passionately delivered a victim impact statement against murderer Bryan Kohberger on Tuesday morning during the sentencing at Boise’s Ada County Courthouse.

According to FOX News Digital, Stevenson reminded Kohberger that her sister and her close friend, Madison Mogen, were not for him to take, stating, “They were not yours to study, to stalk, or to silence.”

“They are everything that you could never be — loved, accepted, vibrant, accomplished, brave and powerful.”

Kohberger sat emotionless in the courtroom, but Alivea delivered blow after blow to the stony-faced killer.

“Disappointments like you thrive on pain, on fear, and on the illusion of power. And I won’t feed your beast,” she said.

“You want the truth? Here’s the one you’ll hate the most: If you hadn’t attacked them in their sleep, in the middle of the night like a predator, Kaylee would have kicked your f–king a–.”

Kohberger remained silent until the judge asked him if her wanted a chance to speak.

“I respectfully decline,” Kohberger said.

As CrimeOnline previously reported, to avoid the death penalty, Kohberger, 30, admitted to fatally stabbing Ethan Chapin, Xana Kernodle, Madison Mogen, and Kaylee Goncalves on November 13, 2022, at the women’s off-campus home.

The plea deal means Kohberger will serve life in prison without the possibility of parole. He also waived his right to appeal.

Kohberger also pleaded guilty to burglary, which is a 10-year sentence.

Before Wednesday’s plea, Kohberger’s attorneys claimed he was not at the crime scene and was driving around alone the night the four students were fatally stabbed.

Late last month, Judge Steven Hippler rejected the defense’s list of four “alternative perpetrators” whose names have not been released to the public.

Police claimed Kohberger visited the area 12 times before the slayings, and that he turned off his phone on the night in question. Kohberger’s DNA was found on a knife sheath located near Mogen and Goncalves’ bodies, according to prosecutors.

The murder weapon has not been found.
