Long Shot: The weight and age of the missing matches with the UID and there is a connection to NYC. The UID's race is pretty ambiguous so it
is possible that she might be of Asian descent. There have been cases where the race of a Doe was incorrectly identified and was later found to be something completely different after further analysis. It's possible Jaisle for unclear circumstances went back to New York, did whatever for a year, and then died in late '99 or early '00.
My gut tells me that the unidentified woman has not been reported missing for whatever reason, meaning she isn't in Namus or other MP sites.
