Were the heal prick blood samples of MM used as a reference DNA sample

[G-Unit]

This saliva was from England. Was any DNA belonging to Madeleine found in the apartment?

Did anything found in Portugal match with the profile?

Some of the hairs might have belonged to her or the twins. Using mitochondrial DNA analysis Kate had the most hairs; 53, so some of them could have belonged to the children. Although some IVF processes result in male mitochondrial DNA surviving, whereas it's destroyed during natural conception. I don't know why the hairs weren't DNA tested for more exact matches.

OK, so what samples collected from the apartment matched up with the profile obtained from the saliva sample ?

Strawman!

By comparing the profile from the saliva with the profiles of Kate and Gerry, it was possible, certainly, to establish that the profile was a (female!) child of the couple.

Kate and Gerry have only one (other) daughter.  Her profile was different (from that of her older sister).

Ergo, they had Madeleine's DNA.

[G-Unit]

By the Portuguese, no.

Letter to the National Forensics Institute (INML) from Goncalo Amaral


17th August 2007

The present inquiry is in relation to the investigation of the disappearance of Madeleine McCann on 3rd May from P da L.

The English authorities in possession of elements collected from the family home in Leicestershire, which are being examined in an unidentified laboratory, traced the girl's DNA profile, in annex to this document.

As it is necessary to the investigation we request the following:

1. Whether in the tests done by the INML Madeleine's profile was established?

2. In the case of a positive answer to point 1, that it should be determined whether the girl is the daughter of the parents identified ? Gerald Patrick McCann and Kate Healy.

3. Information about whether the profile obtained by the INML corresponds to the profile traced in the English laboratory, on the request of the British authorities.

4. If there are differences between the English and Portuguese profiles that a report should be drawn up for this inquiry.

5. In the follow-up of point 4, we request to be informed whether in the English profile the girl is the daughter of the McCann couple.

6. Other information that might be of use to the investigation.

Reply to Queries

- We inform you that none of the samples received by this institute were designated as supposedly belonging to the missing girl and we therefore, cannot reply to this query.


- Samples were studied - hair and a piece of cloth - nuclear DNA profiles only being obtained from 4 samples, which upon comparison with the DNA profiles of Kate and Gerry, could not belong to the girl.

- The samples were then studied using mitochondrial DNA analysis, the same was done for the other samples, giving the results in accordance with our report of 9th July No. 2007/000226 LX-BC.

- As requested in point 5, it was determined that the profile obtained by the British lab could belong to a son/daughter of the McCanns.

- The comparison of the profiles obtained in autossomic STR from Kate and Gerry McCann with the profile obtained was carried out.

By the British (3 months later!) using saliva of Madeleine's provided by Gerry, yes!

The pillowcase was received by the FSS on 22nd May 2007. We don't know who provided it, but Gerry McCann was in Rothley on 21st May.

That wasn't my original  question, which was - did they find any of Madeleine's DNA in the apartment ?

The Portuguese didn't (see my quote above).

[jassi]

The Portuguese didn't (see my quote above).

Jeez, this is like pulling teeth. Did ANYONE find conclusive and definitive evidence of Madeleine's DNA in the apartment?

[ferryman]

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.

(John Lowe)

YES!

[G-Unit]

What?

We haven't been told who collected the pillowcase but Gerry McCann was in Rothley on 21st May and the FSS received it on 22nd. A few reasons have been given for the trip home, but the pillowcase hasn't been mentioned by the McCanns.

As someone pointed out MM's DNA should have been in many locations in the apartment so they would not waste time looking for general DNA findings, just specific ones e.g DNA in a blood spot sample.
But I know what you mean for there is now this line of thought, by some, that Madeleine was never in the apartment at all.

[ferryman]

Jeez, this is like pulling teeth. Did ANYONE find conclusive and definitive evidence of Madeleine's DNA in the apartment?

The Poruguese didn't.

The English (examining a badly contaminated crime-scene 3 months after the crime) might have.

Either way, that's irrelevant.

The British (certainly) established Madeleine's DNA by other means (the saliva of Madeleine's, given to them by Gerry from the pillow of Madeleine's bed at her home in Rothley).

[Robittybob1]

Strange. Perhaps DNA analysis is not all its cracked up to be.

It is always compared to an unrelated person.  DNA testing of this type would not be so good in closely related persons.

[Robittybob1]

What? http://dna-view.com/profile.htm

the word "unrelated person" is always used in the DNA comparisons eg "either the suspect contributed the evidence, or an unlikely coincidence happened – the once-in-7000 coincidence that an unrelated person would by chance have the same DNA profile as that obtained from the evidence".

Re: Abduction of Madeleine McCann on 3rd May 2007

A DNA profile has been obtained from the reference samples of Amelie Eve McCANN (SBM/2) and Sean Michael McCANN (SBM/3).

In this case, all of the bands present in the profiles of both Amelie McCANN and Sean McCANN are represented in the combined profiles of Kate HEALY and Gerald McCANN. This is what I would expect to find if Amelie McCANN and Sean Michael McCANN were their natural children.

Neither the DNA profile of Amelie McCANN nor Sean McCANN matches that from the pillowcase (SJM/1) and therefore in my opinion, neither Amelie McCANN nor Sean McCANN can be the source of this profile.

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,
