I am not a professional in this line of work but just a volunteer at Locate working on UIDs and, more recently, missing persons in my spare time. So far, almost all our cases are of people missing or found in the UK but we do get involved in cases overseas as well if requested to do so, though to a lesser extent.
There have been various cases in the US of people being identified but not named by the authorities so the identity of this woman being disclosed is not a given. I wonder how well known this particular case really is after almost 40s years. Yes, it's a fairly well known case on here but I don't recall hearing about it elsewhere, eg in podcasts.
ETA that the day job is corporate governance.
