It is reported today that bill for the Scotland Yard Police put on the Maddie case in May, 2011 has now risen to £4.5 million, and with more to come. There has been no positive result so far, as the sixth anniversary of the crime looms on 3rd May.
How much more will be spent on what appears to be a fruitless exercise?
If Maddie is in the hands of abductors it is unlikely they would allow her anywhere that she could be recognised, and would also take every step to disguise her. By now Maddie herself would probably have been conditioned to the life style of her abductors and could well have forgotten her previous existence prior to 3 May 2007. A positive DNA test would be the only evidence of her identity, and it would certainly be very difficult for her to integrate back into her own family.
Assuming that she is still alive, there is an argument for her to be left with her abductors and hope that she has a good and fruitful life in her new environment.
