It seems the DNA results should be back. Doesn't it usually only take a few days to identify a body by doing a DNA match? I've seen it take as little as one or two days. Maybe results will be in today? One can hope...
Those are cases where the identity of a deceased is known, or strongly suspected, then it's a one-on-one match. A profile can be derived from a personal item, a toothbrush, for instance. Like Bella Bond. A hairbrush and a nasal syringe were recovered in a search of the mother's apartment, so a preliminary match was made rather quickly. When the identity of the deceased is a complete mystery, or if there is no source from which to extract a useful direct sample, then a comparison has to be made to DNA from family members. That's more complicated, and always takes longer. We also have to consider that the child's remains are only partial, and badly decomposed, at that. The quality and type of DNA available, nuclear or mitochondrial, is a factor to consider.
Here's an example. Last night I came across an article about a child whose skeletal remains were found in Utah back in 1996. In November 2013, the Juab County Sheriff's office sent a bone was sent to the University of North Texas for analysis. In January 2014, they were notified of a match to the child's mother. So that was two or three months.
The article also talked about a deceased woman who'd been unidentified for years. A hair sample was sent to the same lab in 2014. The results just came back August 22, a mitochondrial match to a family member.
There are many cases like that here in the Unidentified forum where members keep checking back, waiting for an update. Tammy Jo Alexander comes to mind. The turnaround time was four or five months. With Grateful Doe, it's been several months, and still no word.
Also, are we sure they have a complete profile of the little toddler? I know it was mentioned in at least one article, but I don't recall exactly what it said. I'll have to look for it.
