Dunno. First learned of it 25 years ago; last saw it referenced (as valid) about five or so years ago I think.
I did a little googling: Here's a link to her book. The local rag did a lengthy article about her in 1992 here.
Biblical Archaeology Review published an article by her in Jan, 2002.
She was also lecturing on it in 2002, here.
Seems to me it's certainly still in play.
