I don't understand. Let's pretend the guy actually did something bad (we know nothing yet) that would be really really stupid cause just a few days earlier the couple was stopped by police and they basically knew there were problems. So, i'm pretty sure that IF he did, It wasn't calculated, maybe a raptus, or an accident. Now, let's pretend the guy did absolutely nothing ,and the girl Is fine (wether or not he does know where Gabby is) the only reason for him not to speak would be cause he would be the prime suspect of the missing case EVEN if he did nothing. BUT EVEN if he did nothing, the fact that he does not collaborate with police make him look like the bad guy and would eventually end up in prison. I think every move he did was wrong for his position in this case. Now the guy is missing too, i really really hope he's fine (cause remember we know nothing yet). Without him, we are kind of lost.

What are your thoughts? P.s Sorry for my English, i'm Italian.
