I also have found absolutely nothing on her disappearance. It’s be one thing if this was a cold case from the 50’s in a remote part of the country…
Can I ask a few questions? (maybe answers could help a few WS’s who are much more talented than me):
-Did you know her from high school or college?
-Did she grow up in Sylmar?
-Did you her family?
-When did you become aware that she had gone missing?
-When you knew her, was she single or married (is JMW a married name?)
-Do you know if she was living with anybody at the time of her disappearance?
-Was her disappearance in the news? (Maybe somebody on WS knows how to check newspaper archives / databases for the week or two after she went missing).
-Do you know who reported her missing?
Anything that might help
