She is now "at lab for extraction." Per her Namus, she is believed to have died 2009-2017, up to 10 years per DDP. She is described by DDP as being of mixed black and French Cajun heritage. This may be a difficult case, as non-white DNA is underrepresented on GEDMatch, and my understanding is that Cajun ancestry has undergone some bottlenecks and familial marriages in the past, which can be difficult to parse out in terms of genetic genealogy. It does certainly sound like this was very much a local woman, or at least someone with roots in Louisiana. Here's some info
about a genetic disorder that's being found in nearby Acadia Parish and the underlying genetics of the area.
During the search for her identity, area farmers who owned the land told investigators a guy who owned a farm nearby may have been involved with high risk females.
This seems to imply possible foul play on the part of this individual, or at least that they'd be open to dumping/burying a body of someone who died of overdose or other causes. It doesn't seem that her cause of death is known or at least hasn't been released to the public.
