Perhaps they were tired of all the working, scrimping & saving, and someone "made them an offer they couldn't refuse". I dunno.Your comment is very relevant. When I first saw the CCTV image my gut instinct was that they were walking to meet someone for a bit of 'business'. I feel they have that air about them, but it's just a hunch. I also thought they wouldn't look out of place travelling by boat or air with the businessman-type. Those were my first impressions of the CCTV image.
