Let's analyze it coldly. We're in 2007. PDL is a cell antenna. Nearest ones are some 10Km away. Every mobile uses a single antenna, the nearest one if available.
This is the info police can have from operators. CB lived in an area covered by PDL.
German prosecutor found a number that might belong to CB. Asks for detailed log offered by Portuguese police and held by Met.
His number is there. And did a call at 7.32pm the day Maddie disappeared.
Forensic conclusions:
- Mobile highly likely to be his
- Mobile was covered by PDL antenna on May 3, 2007 at 7.32pm, time a call started (unless nearer antenna unavailable).
You can do this with well upwards of 1,000 people at least, of which I'd guess some 5-10% had a call up to 3 hours before disappearance.
There's a lot of guess work in
your analysis. Law Enforcement wouldn't be pursuing this line of enquiry unless they had much more 'substance' then your analysis suggests.
