IMO it was a planned abduction. There are sightings of people who could match CB’s description on or around 3 May - JJ and CT sightings I think are relevant, especially the latter when compared to the footage of CB wearing sunglasses in the Malaga footage.
I don’t think that CB would have needed to do this kind of preparation to steal a camera or pocket change, I feel as though burglary would have been an opportunistic crime for him - easy pickings in tourist areas.
We know from the rape of the 72 year old that he planned attacks and in this and HB (if this was him) he carried a bag. There is, what I think a very big difference with these cases compared to MM (Other than the obvious adult vs child, rape vs abduction) which is that he planned to commit these crimes in the victim’s homes. This means that he was taking objects in, not necessarily to break in but for use in the crime - restraints, camera ... goodness knows what else but I’m sure it’s been reported.
In a planned abduction, IMO, I don’t think someone with CB’s skill set needed a bag full of pri-bars and hammers to get into 5A, especially considering the back patio doors were definitely open, the window may have been open, the front door may have been unlocked and the keys to 5A were lost in the days prior to 3 May.
