Brian did not evade law enforcement prior to his going missing. LE knew where he was. They could have picked him up at any time.
I do think it is possible Brian confessed to his parents at some point. If so, I expect that information to be shared with the media and/or the Petito family eventually. Might as well at this point.
I agree. There was no evading once BL was home.
I am, however, very unhappy with how NPPD and the FBI handled surveillance of BL once he was at home. There is no way on earth he should have been able to go "hiking" without LE knowing about it and following him. Even worse, when contacted by SB that BL had not returned home that evening the FBI apparently didn't react at all, otherwise, he almost certainly could have been found the following day. Meanwhile NPPD was busy tailing some guy in Tampa. What a mess. I am extremely pro-LE, but they don't get a pass on this situation which was 100% their fault for not having BL under surveillance from the time that they knew GP was missing and that BL had driven her van back to his parents home alone. I don't even want to get started on the search for BL.
