That was in the days following BKs arrest. SG cited an Instagram account that was quickly disproven.I am in total agreement with you. The point of my post was that 48 hours is putting out a new episode as if this was new information. SG stated this months ago, soon after BK was arrested.
He noticeably softened his initial stance in subsequent interviews…

Idaho murder victim's family searching for connection to Bryan Kohberger
Kohberger was arrested on December 30 and charged with four counts of first-degree murder but has maintained his innocence.

If you poke around in the weeks following there are other interviews where he sounds nowhere as confident and seems to dodge the direct question. Before he stops talking about it all together.
48 hours wants to tease us to watch and loves clickbait…but for them to be the last one to the party and give us a dud? Their prodcuers live eat and breathe true crime.
So I’m going to go out on a limb and say he found either evidence of something new or evidence to back what he believed before.
MOO
