If quadruple murderer Bryan Kohberger felt anything as the friends and families of his victims excoriated him with a series of increasingly fiery witness impact statements, he did not show it.

Kohberger was today handed four consecutive life sentences plus ten years for felony burglary. The sentencing came at the end of a three-hour hearing during which the killer fixed each person who stood to address him in Ada County Courthouse with the same intense stare.

It is two and a half years since Kohberger entered 1122 King Road in Moscow, Idaho shortly after 4am and stabbed 21-year-old best friends Kaylee Goncalves and Maddie Mogen and 20-year-old Xana Kernodle and her boyfriend Ethan Chapin to death.

Yet today he didn't flinch as he faced down the devastation his crimes have wrought - not even when Kaylee's father, Steve Goncalves, dragged the lectern from where it stood facing the judge and turned it, like a tank's gun tower, towards him.

Goncalves had been vocal in his disagreement with the plea deal struck by Kohberger earlier this month - a move that saw him avoid trial and with it the threat of the death penalty.
