Re: Abduction of Madeleine McCann on 3rd May 2007

A DNA profile has been obtained from the reference samples of Kate HEALY (51162896) and Gerald McCANN (511622897).

A DNA profile has also been obtained from a pillowcase (SJM/1).

DNA profiling reveals a series of bands, half of which a child inherits from their natural mother (maternal) and half of which it inherits from their natural father (paternal).

In this case, all of the bands present in the profile of obtained from the pillowcase are represented in the combined profiles of Kate HEALY and Gerald McCANN. This what I would expect to find in the profile obtained from the pillowcase originated from a natural child of theirs.

The results of the DNA profile obtained from the pillowcase is approximately 29 million times more likely if the profile originates from a natural child of theirs rather than someone unrelated to them.

In my opinion, the results detailed above provide extremely strong support for the view that the profile obtained from the pillowcase originates from a natural child of Kate HEALY and Gerald McCANN.

Please note: I understand that the McCANN – s have a second female child. It therefore remains a formal possibility that the DNA on the pillowcase could have originated from her as the genetics would be in keeping with those described above.

If I can be of further assistance or you require a CJA statement please do not hesitate to contact me at the laboratory on 01937 548287.
