Stuart

Firstly, here are the last three results you are expecting :



An incomplete DNA result was obtained from cellular material on the swab 3a. The swab contained very little information and showed low level indications of DNA from more than one person. However, all of the confirmed DNA components within this result match the corresponding components in the DNA profile of Madeline McCann. LCN DNA profiling is highly sensitive it is not possible to attribute this DNA profile to a particular body fluid.



There is no evidence to support the view that Madeline MCCann contributed DNA to the swab 3B.



A complex LCN DNA result which appeared to have originated from at least three people was obtained from cellular material recovered from the luggage compartment section 286C 2007 CRL10 (2) area 2. Within the DNA profile of Madeline McCann there are 20 DNA components represented by 19 peaks on a chart. At one of the areas of DNA we routinely examine Madeleine has inherited the same DNA component from both parents; this appears therefore as 1 peak rather than 2, hence 19 rather than 20. Of these 19 components 15 are present within the result from this item; there are 37 components in total. There are 37 components because there are at least 3 contributors; but there could be up to five contributors. In my opinion therefore this result is too complex for meaningful interpretation/inclusion.



Why - ...



Well lets look at the question that is being asked :

"Is there DNA from Madeline on the swab "
It would be very simple to say "yes" simply because of the number of components within the result that are also in her reference sample.


What we need to consider, as scientists, is whether the match is genuine and legitimate; because Madeline has deposited DNA as a result of being in the car or whether Madeline merely appears to match the result by chance. The individual components in Madeline's profile are not unique to her, it is the specific combination of 19 components that makes her profile unique above all others. Elements of Madeline's profile are also present within the the profiles of many of the scientists here in Birmingham, myself included. it's important to stress that 50% of Madeline's profile will be shared with each parent. It is not possible in a mixture of more than two people, to determine or evaluate which specific DNA components pair with each other. Namely, we cannot separate the components out into 3 individual DNA profiles.



Therefore, we cannot answer the question: is the match genuine or is it a chance match.

The same applies to any result that is quoted as being too complex for meaningful inclusion/interpretation.


What questions will we never be able to answer with LCN DNA profiling -



When was the DNA deposited -

How was the DNA deposited -

What body fluid(s) does the DIVA originate from -

Was a crime committed -


These, along with all other results, will be formalised in a final report

DNA  Forensic Report - 06.07.2007

This report summarises the results of DNA profiling tests conducted on a number of samples submitted to the Birmingham laboratory of the Forensic Science Service(R) from the Leicestershire Constabulary on behalf of the Pol - ia Judiciaria and Laboratorio De Policia Cientifica on 7th August 2007 This report is marked for the attention of Detective Superintendent Prior; however I understand and accept that the contents of this report will be shared with the necessary authorities in Portugal.

I have received from my colleague, Sarah Vraitch, copies of the reference DNA profiles of Gerald McCann (CB/1), Kate Healy (CB/2), Amelie McCann (SBM/2) and Sean McCann (SBM/3). I have also received a copy of the DNA profile obtained from the possible saliva staining on the pillow case (SJM/1) which is assumed to be the DNA profile of Madeleine McCann.

A weak incomplete DNA result which consisted of only a few unconfirmed DNA components was obtained from cellular material on the swab (3A) from the apartment floor. An attempt to obtain a DNA profile from any cellular material on the wet swab (3B) from the same area was unsuccessful in that no profile was obtained.

Weak and incomplete DNA results which consisted of only a few unconfirmed DNA components were obtained from cellular material on the wet and dry swabs (14A & B} from the back of the sofa.

A weak and incomplete DNA result which showed indications of having originated from more than one person was obtained from cellular material on the dry swab (15A) from the back of the sofa.

A DNA result which appeared to have originated from at least three people and which appeared to have originated from at least two males who had contributed the majority of the DNA was obtained from cellular material obtained from the wet swab of the sofa (15B). in my opinion there is no evidence to support the view that Gerald McCann or Madeline McCann contributed DNA to this result. The DNA from this swab has not been subjected to LCN DNA profiling tests.

A weak incomplete DNA result which consisted of only a few unconfirmed DNA components was obtained from cellular material recovered from the edges of tile 2 286/2007-CRL(2) from the apartment floor. An attempt to obtain a DNA profile from any cellular material recovered from a further area on tile 2 and two areas on tile 3 (286/2007-CRL(3) were unsuccessful in that no profiles were obtained.

A weak incomplete DNA result which consisted of only two unconfirmed DNA components was obtained from cellular material recovered from the hem of one of the blue curtains 286A/2007-CRL(16(2)) from the apartment.

An attempt to obtain a DNA profile from any cellular material recovered from one area of the plastic luggage component (286C/2007-CRL(10(2))) from the motor vehicle was unsuccessful in that no DNA profiles were obtained.

A low level mixed DNA result which appeared to have originated from at least two people was obtained from a second area of the plastic luggage component (286C/2007-CRL(10(2))) from the motor vehicle. In my opinion this result is too complex to interpret at this stage.

A low level mixed DNA result which appeared to have originated from at least three people was obtained from cellular material recovered from the fibre coated luggage component (286C/2007-CRL(10(1))) from the motor vehicle. In my opinion this result is too complex to interpret at this stage.

A low level incomplete DNA profile which matched the corresponding components in the DNA profile of Gerald McCann was obtained from cellular material on the key card (286C/2007-CRL(12)). This sample has not been sent for further testing using LCN DNA profiling tests.

Low level incomplete DNA results, which in certain circumstances showed a contribution of DNA from more than one person were obtained from biological material on the following swabs: 286A/2007 CRL 14a, 14b, 15a; the swab from the hem of the curtain 286A/2007 CRL 16 curtain 2; the swabs from the tile pieces 286/2007 CRL 2 areas 1 and 2 and 3 area 1. In my opinion there is no evidence to support the view that anyone from the McCann family contributed their DNA to them results.

An attempt to obtain an LCN DNA result from any cellular material on the swab from area one of the luggage compartment section (286C/2007 CRL 10) was unsuccesful in that no profile was obtained.

An incomplete LCN DNA result which appeared to have originated from a male was obtained from cellular material from the swab (286A/2007 CRL 1a & b). The profile did not match any of those previously tested in this case.

An incomplete LCN DNA result which appeared to have originated from a female was obtained from cellular material from the swab (286A/2007 CRL 4a & b). The profile did not match any of those previously tested in this case.

An incomplete LCN DNA result which appeared to have originated from a male was obtained from cellular material from the swab (286A12007 CRL 9a & b). The profile did not match any of those previously tested in this case. Furthermore, it did not match the profile obtained from the swab, 286A/2007 CRL 1a & b.

Mixed LCN DNA results which appeared to have originated from at least two people were obtained from cellular material recovered from the swabs (286A/2007 CRL 2a & b, 5a 7 b, 7a & b, 10a & b and 12a & b). in my opinion there is not evidence to support the view that any of the McCann family contributed DNA to Yhis result.

Attempts to obtain an LCN DNA result from any cellular material on the swabs 286A/2007 CRL 11a & b & 13a & b and from tile pieces 286/2007 CRL 3 area 2 were unsuccessful in that no DNA profiles were obtained; possibly due to the absence of sufficient good quality DNA.

LCN DNA results which contained too little information for meaningful interpretation were obtained from cellular material on the swabs 286A/2007 CRL 6a & b and 8a & b).
LCN DNA results which appeared to have originated from at least three people and which were too complex for meaningful interpretation were obtained from cellular material recovered from the swabs taken from the tiles 286/2007 CRL 1, 6, 7,8, 10 & 11).

An attempt to obtain an LCN DNA result from any cellular material on the swabs from the tiles 286/2007 CR/L 5 stains 1, 2 & 3 were unsuccessful in that no DNA profile was obtained.

An LCN DNA result which contained to little information for meaningful interpretation was obtained from cellular material on the swab from the tile (286/2007 CR/L 9).

Low level LCN DNA results were obtained from cellular material on the swabs from the tiles (286/2007 CR/L 4 & 12). In my opinion there is no evidence to support the view that anyone in the McCann Family contributed DNA to these results.

An incomplete DNA result was obtained from cellular material on the swab (286A/2007 CRL 3a). The swab contained very little information and showed low level indications of DNA from more than one person. However, all of the confirmed DNA components within this result match the corresponding components in the DNA profile of Madeline McCann. LCN DNA profiling is highly sensitive; it is not possible attribute this DNA profile to a particular body fluid.

A low level LCN DNA result was obtained from cellular material on the swab (286A/2007 CRL 3b). In my opinion there is no evidence to support the view that Madeleine McCann contributed DNA to this result.

A complex LCN DNA result which appeared to have originated from at least three people was obtained from cellular material recovered from the luggage compartment section 286C 2007 CRL10 (2) area 2. In my opinion this result is too complex for meaningful interpretation.

The curtains (286A/2007 - CR/L 16 and 16B) and the piece of white curtain (286B/2007 - CR/L 1) and the fragments of bushes (286/2007 CR/L 21) were examined for the presence of blood. No blood was found.

The small fragments of tile, and bags of dust and cement glue (286/2007 CR/L 13, 14, 15, 16, 17, 18, 19 & 20) were not examined at the laboratory.

if I can be of further assistance please do not hesitate to contact me at the laboratory.
Yours sincerely,

Le rapport mentionne 15/19 matches of Madeleine DNA profile

This serves to add [to the case file] a laboratory examination report prepared in England, written in English and translated into Portuguese, delivered to this police force on 4 September 2007 by English police officer Stuart Prior.

This laboratory report tells about the examinations made of two trace evidence recoveries, one behind the living room sofa in apartment 5A and the other in the boot area of the vehicle used by the McCann family, hired [by them] from the end of May this year.

In some of these recoveries (samples) DNA was found whose components are also found in the profile of Madeleine McCann. 








With respect to the trace evidence recovered behind the sofa all the confirmed DNA components coincide with corresponding components in the DNA profile of Madeleine McCann.

In the sample collected in the boot area of the vehicle, 15 of the identified DNA components coincide with the corresponding components in the DNA profile of Madeleine McCann, this of [having] 19 components.
