News on testing used to identify the unidentified
New test can more closely pinpoint birth date and death date
I wasn't sure where to post this but it makes the most sense in the UID section.
Just came across this article from sciencedaily.com in which a new test has been developed to help identify UIDs. One thing we all struggle with here is the age of the deceased - how many times have we found out that estimated age was way wrong?
It uses radiocarbon analysis. Someone with a better understanding of "science stuff", or better comprehension at least than I have right now lol, will have to give a better summary than me, but here's a brief explanation:
"In 1968, a child's cranium was recovered from the banks of a northern Canadian river. Initial analysis conducted by investigators, using technology at the time, concluded that the cranium came from the body of a 7-9-year-old child and no identity could be determined. The case went cold and was reopened later.
The cranium underwent reanalysis at the Centre for Forensic Research, Simon Fraser University in Canada, where skull measurements, skeletal ossification, and dental formation indicated an age-at-death of approximately 4 1/2; years old. At Lawrence Livermore, researchers conducted radiocarbon analysis of enamel from two teeth indicated a more precise birth date. Forensic DNA analysis, conducted at Simon Fraser University, indicated the child was a male, and the obtained mitochondrial profile matched a living maternal relative to the presumed missing child."
"Age determination of unknown human bodies is important in the setting of a crime investigation or a mass disaster, because the age at death, birth date and year of death, as well as gender, can guide investigators to the correct identity among a large number of possible matches."
Birth or death would have to have happened in the 50s and 60s, because of some stuff going on in the world (can't type out the word, at work). I THINK. Someone will have to read it and verify. Interesting and helpful information, nonetheless.

Everything is MOO and I am always willing to be wrong!
October 2013 marked 60 years since Evelyn Hartley's violent kidnapping while babysitting.
We need fresh eyes in the case - please visit us in Evelyn's thread!

I'm going to stick this thread for a time so our regulars get a chance to read it and then we'll be moving it to the UID Reference forum found here ----->Unidentified "How To" & Reference Forum - Websleuths Crime Sleuthing Community

CT scans could bolster forensic database to ID UID
A study from North Carolina State University finds that data from CT scans can be incorporated into a growing forensic database to help determine the ancestry and sex of unidentified remains. The finding may also have clinical applications for craniofacial surgeons.

FL - Dozens Of Unidentified Bodies
WEST PALM BEACH, Fla. - Sheriff's investigators say they have numerous unidentified bodies that were recovered in Palm Beach County in the 70's, 80's and early 90's.
Just figuring out who they are, let alone who killed them or how they died, can be a challenge.
In one case, they're making progress.
