FL FL - Volusia Co, UnsFem UP1308, 25-40, remains at 760 Pringle Rd, Feb'80

[DS2021]

Pinky and the JD both have DNA tests completed in Namus so they would have been picked up as a match already.

I believe they would need to both have the same type of DNA on file. If one has mtDNA and the other has Nuclear, I dont THINK they would match up. Unfortunately we have no way to confirm which cases have what type of DNA on file

From a separate thread, addressed here to avoid going off-topic.



I was told by Hal Brown (from the Delaware State MedEx Office) that Family Reference Samples (FRS) are processed entirely by an automated system, and any nucDNA samples taken from maternal relatives are also processed for mtDNA.

However, if only paternal relatives are available (e.g., Mindi Chambers), no mtDNA profile can be developed.

Also, if the unidentified body is too badly degraded, they might not be able to extract nucDNA even if they are able to extract mtDNA. As I understand it, mtDNA is more resistant to degradation than nucDNA.

Also, although it is often denied that there are known instances of false negatives in CODIS, I know of one instance where DNA was available in CODIS for both the MP and the UID, and a hit was not triggered.

Dawn Renee Higdon of Ridgecrest CA went missing in Aug'88 and her skeletal remains were found in Jul'90 in San Bernadino County.

Here is the link to info regarding Dawn (no info is available about the previously unidentified remains)
http://forthelost.wordpress.com/2010/08/02/dawn-higdon-missing-twenty-two-years/

These cases remained unmatched despite the existence of a single FRS from one of Dawn's relatives, and a DNA profile for the UID in CODIS. (I'm not sure whether they were nucDNA or mtDNA, or whether the single relative was maternal or paternal). It was only after additional relatives submitted FRS samples that a feature in CODIS called "Pedigree Tree" evaluated the multiple samples collectively and then was able to flag the match to the UID case.

Here is some additional info from David Van Norman in response to two questions that I posed to him. My questions were:

(1) Is it a correct assumption that If only a mtDNA sample is available for a missing person, and only a nucDNA sample was available for the unidentified decedent, CODIS would not be able to identify the match?

(2) If only one sample of familial nucDNA is available to compare to the nucDNA of the UID, is there a significant risk of a false negative?

He responded as follows:

Answer #1: Correct nucDNA = apples and mtDNA = oranges! Or nucDNA is BluRay and mtDNA is VHS. The problem is Californias lab philosophy to develop nucDNA first (because it gives a higher confidence chance of a match and positive ID), whereas other labs go for mtDNA first.

Answer #2: Correct In fact if there is only one familial sample submitted for a missing case, so I am told by the folks at UNT, CODIS will not even bother comparing that profile against UHR due to the sheer volume of matches it will elicit. They require two or more to search. Sadly, they arent advertising that so cops who watch too much TV stupidly continue to submit just one family member when many are available. I had an LAPD detective tell me that they didnt have to sample the mother of a missing mans child since she contributed nothing to his DNA. Apparently he hadnt heard about exclusionary samples. (PS That childs DNA was subsequently matched by a cold DNA hit to skeletal remains found after a fire near Griffith Park).

This info is from 2011, but I would imagine a lot of it still applies
