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 (51162897).

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 inherits from their natural father 
(paternal)

In this case, all of the bands present in the prof – e of abtained from the pillowcase are 
represented in the combined profiles of Kate HEALY and Gerald McCANN. This is 
what I would expect to find if 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 form 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 originated 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.

Yours sincerely
