My understanding is BK agreed to plead guilty to the four murders, accept LWOP, and waive any right to future appeals.
I am not happy with this plea deal, but BK can now live the rest of his life, rotting away in prison, and despite wanting to live in infamy, he will, in time, be forgotten, at least his name will be. When books are written about him, they will show him as an inept killer, who left enough bread crumbs behind, that the Keystone Cops could have caught him. He will never be on the Mt Rushmore of serial killers. The man who thought he was the smartest man in any room, can now live the rest of his life trying to convince himself that he is the smartest man in his maximum-security cellblock.
To the surviving roommates, the friends who went to the house that morning, the first responders, the DD driver, and mostly, to the families of Kaylee Goncalves, Madison Mogen, Xana Kernodle, and Ethan Chapin, know that despite the evil in the world, there is so much more goodness, and millions of people will continue to lift you up in prayer and good thoughts, as you can finally begin the next phase of your lives, putting this part behind you as much as possible, and looking ahead, always remembering the way your loved ones lived, and not the way they died. God bless you all. JMO
