I've pondered this as well, all along...
Since BK was arrested and his PA PD said he seemed "calm".
When he didn't declare his innocence outright or give an alibi to LE or his PD.
When his PA PD said
"He called the charges "a little out of character.... He said this is not him. He believes he's going to be exonerated. That's what he believes, those were his words.". Public defender says Idaho murder suspect is ‘calm,’ believes he’ll be exonerated: ‘This is not him’
IMO, there couldn't have been a more carefully worded 'non response' for an accused quadruple murderer to say after being arrested and taken into custody.
Then the standing silent/no active plea when he was requested to state his plea in court, which he didn't do, but still got a default one (not guilty plea entered by the court instead of him).
None of that added up to anything concrete in terms of an alibi, IMO.
And since the beginning, if true (I realize it's not proven and there is no source, so MOO) that he asked LEOs who arrested him if they had arrested anyone else, that implied to me he knew someone else had some some knowledge of the lead up to and/or commission of the murders.
Not necessarily an accomplice but more of an aider and/or abetter.
Whom will "show up" in some way in the evidence/data collected by LE during their investigation.
Whom he set up to take some blame or deflect from him doing everything himself.
Or with whom he arranged some squirrelly ruse to have some itsy bitsy piece of evidence planted, which probably can't be proven as 100% true, as to where he was or wasn't during the timeframe of their murders.
For example:
"Jane Doe was on a messageboard/online forum with me from 3:45 am to 4:30 am on November 13th, and the forum will have a record of my messages with time/date stamp, and the IP address of my computer/device I was using, and there will be retrievable(?) data on me accessing wifi or celltower data during that time, and it will show it (the device) was located in Pullman at the time."
And his former PD said this 2 1/2 months ago, that he doesn't expect BK's "stance" to change (
BBM):
"With the news of suspected killer Bryan Kohberger's recent Grand Jury indictment, Monroe County public defender Jason LaBar says he doesn't think it changes anything for his former client, who said he was eager to get back to Idaho to be exonerated.
"This indictment is really just the formal charging instrument against Bryan. It's just formalizing the allegations. Idaho will still have to prove him guilty beyond a reasonable doubt, so I think his stance would remain the same," LaBar said."

All MOO
