Planned abduction vs Opportunist crime.
RSBM - top post.
Just replying on these 2 points.
1. CB is no mastermind. If we look at his track record, his known crimes are mostly opportunistic. The DM rape did require some advance planning, but nothing to the level of what abducting MM would have. DM lived in an isolated villa on her own. He broke in dressed in head to toe gear to avoid leaving DNA, attacked her in privacy, then left her there.
Agreed. This guy is small time, who routinely takes big risks and gets caught. I find it highly unlikely he was part of any people smuggling gang.
2. How could an effective plan really be put together? With MM, he had to work out the movements of various members of the Tapas group who seemed to have quite random checking times. This in a holiday resort with other holiday makers also walking around. He had to get in, carry MM and exit without wakingher. Either out of the window (awkward) or through a door, which he then closed behind him while still carrying her. Then get her to a safe place without being seen. Now I'm not saying those things couldn't have happened but however good the plan, he would have always being relying on some level of luck throughout to not be noticed. Plus, how would he have managed to gather all this intel of the tapas group's routines? Hanging around on the corner each night watching everything would have looked a bit suspect. He might have had insider knowledge but again, how in depth could this be, an OC employee couldn't spend all their time watching the group either. And even if there was an inside source, that doesn't mean that it was with the intention of abduction, someone might have just given him the heads up of when to rob it.
This has always been my beef with the tabloid style stories of suspicious people lurking around OC keeping apartments under observation.
As you say, he had no way to know when checks would occur, and indeed due to rotation, another check might happen within mins of the last one.
It seems far more likely you would observe the parents leave, and then strike. He had realistically no way to know who was at dinner, or to know which people might check which apartment.
