I got a notice from the NCMEC saying Bertha Sieg has been found dead. She’s been removed from NamUs as well, or at least, I can’t access her profile there. Bertha was a fifteen-year-old girl who disappeared from a city in northern Texas 22 years ago. One of those “few details are available” cases.
I checked and I can’t find anything about this online. I am hoping to get some information before I put a notice up in the resolved page.
R.I.P. Bertha.

From Facebook comments made by her mom I gather that there was a body found in 1994 but wasn’t identified until someone matched the Jane Doe poster to Bertha. Very sad.
From Facebook comments, it looks like she was Jane Doe 1994 from Dallas. https://m.facebook.com/missingorabducted/posts/10151922316555671
