What I don't understand is.........CCTV....... Claudia cannot have walked to work or she would have been seen on CCTV on the same cameras that saw her walking home the day before. Plus, all people and cars passing past Claudia's house [in either direction] can be surely seen on CCTV, in the same way that the "alley man" and the walker by was seen [when alley man stopped in his stride] OR via the other cameras that are situated on the walk to work. There should therefore be a count of cars and people passing, even if they can't be identified. Also, of the time that people and cars passed during the night and into the morning hours ????
