Hi, I am intrigued about the lack of forensics you mention, or better what exactly you mean by nuclear DNA that the traces were there.
I checked the PJ files again and have collected the below - the analysis results on hairs and other genetic material collected from 5a
In sum, many unidentified hairs and profiles. the most interesting profile appears to be 'L', which was both present in the spot on the bedspread and in 7 hairs. there was another request for analysis of profile 'L', in Dec 2007: they requested forensic examination of spot found on mattress in 5A.
I understand that people are saying the saliva belonged to a 2year old boy who was staying in 5A before. However I haven't been able to find this identification in the PJ files... and to add to that, as far as I understand only reference samples from the dad were taken...
What I want to say is that there is some material collected from 5a that could be useful? if it is still available that is and not destroyed...
There are also several different fingerprints collected that have not been identified. I am sure they could have done much more, but at least there must be something to work with?

Morphology analysis of the hairs
All hairs received for analysis were subjected to macro- and microscopic characterisation, with the majority of those having the root being in a telogenic phase.
Relating to Apartment no. 5-A
- Envelope No. 1 - "recovered from the floor at the entrance to the children's bedroom" 25 hairs with root; 4 hairs only stem; 3 hairs non-human.
- Envelope No. 2 - "recovered from the floor next to the bed from which the child disappeared" 3 hairs with root; 25 hairs only stem.
- Envelope No. 3 - "recovered from the top of the bed from which the child disappeared" 2 hairs with root; 2 hairs only stem.
- Envelope No. 4 - " recovered from the floor next to the bed that was next to the window in the children's bedroom" ll hairs with root; 4 hairs only stem.
- Envelope no. 6 - "recovered from the floor of the lounge" 26 hairs with root; 4 hairs only stem; l hair non-human.
- Envelope no. 7 - "recovered from the entrance hall at the front door of the apartment" 44 hairs with root; 8 hairs only stem; 6 hairs non-human.
...
Acid Phosphatase Test to detect semen on the small spot on the cloth fragment in envelope no. 5 recovered from the bedspread of the bed next to the window of the children's bedroom: Weakly positive.
Phadebas Forensic test, for detection of saliva on the fragment of cloth corresponding to vestigio n'. 5 collected from the counterpane of the bed next to the window of the children's bedroom: Positive.
Mitochondrial DNA analysis:
1st- The macro- and microscopic analysis of 257 hairs revealed 245 human and 12 non-human.
...
4th- With respect to autosomic STRs the male genetic profile identified from the spot on the cloth fragment (bedspread of the bed next to window in the children's bedroom- Env 5) did not match any profile from the reference samples.
and several which did not match the reference materials:
Profile identified by letter "L", present in the spot on the bedspread of the bed next to the window and in seven hairs, meaning that all these samples came from the same person or from someone having the same maternal bloodline, did not match any of the reference samples.
- Profiles identified by letters "B", "D", "F", "J" and "Q" are different from the above, and from each other, and are distinct from reference samples.
-The remaining 28 samples analysed, of which 17 were recovered from the apartment, showed mitochondrial DNA from different from each other, and distinct from those above.
8th- Of the 245 hairs analysed, no results were obtained from 52.
