Not intending to be snarky. It took me about 15 minutes using the thread links posted on on page 1 of every thread for this case.
Here is where the posts first began here regarding the convicted murderer accepting a plea deal, starting with post #628:
Post in thread 'PLEA DEAL REACHED - 4 Univ of Idaho Students Murdered, Bryan Kohberger Arrested, Moscow, Nov 2022 #109'
PLEA DEAL REACHED - 4 Univ of Idaho Students Murdered, Bryan Kohberger Arrested, Moscow, Nov 2022 #109
The defense reached out to the prosecution, they came to an agreement for the resulting plea deal; source below.
The plea deal — the defense requested an offer from the prosecution — will take the death penalty off the table in exchange for Kohberger pleading guilty to all charges: the four first-degree murder counts and an additional charge of felony burglary.
