But the perp could check the PC later. It is big news in Delphi. Do you imply that they expect him to come to the PC? Has he attended al PCs?
I'd expect him to avoid them.
Also - if they have an idea who he is, they don't need to adjust their schedule to accommodate his. If they hope they know, and think he does not work on Mondays, then they may hope he'll stop by.
Only I don't believe that he does it (attends PCs or taunts them). He is probably anxious and checks all their pressers, follows Twitter, whatever, but I don't think he comes to the PCs. He is really very scared, and - MOO only - he is scared that one day, LE would point at him and say, "here's the man", and he'd be torn into pieces by the crowd. So he avoids the PCs and avoids the PD and probably is in self-imposed solitude. MOO again.
I personally think that he is a very weak person who does not have own personality and like the moon, shines with reflected light. I do have the feeling that he, at least superficially, is a believer, and understands the gravity of the sin. He is not Chris Watts who needed to spend some time in jail to even get "the gravity of what he has done". This one understands, but what prevents him from confiding is the fear of the prison (he is not a social person so predictably, he is very much afraid) and... well, he still enjoys life; maybe he also wants to protect his beloved ones.
But I do think that if he were not so scared, he'd already confide. And I am repeating myself - I would recommend not "the Shack", but Dostoevsky's "Crime and Punishment", and "The Resurrection" by Tolstoy. Criminals can also grow morally and change, and with this change comes the hope of forgiveness. But they can't absolve own sins.
JP, who admitted own fault, to spare JC to go through the trial, ultimately, did a much more courageous thing than Scott P or Chris W. He is a criminal - but he confessed. I feel sorry for him because I read of the incessant bullying he underwent in school, and I think his crime is related to bullying.
I am getting off on a tangent.
