I think I've managed to not follow up on several possible submissions. I'm sorry, I'll get to those soon.
I see Wendy Huggy has been added to the Namus ruleouts list. She fits the main criteria, but no injuries mentioned. I assume they figure she had time to acquire them in the three years between when she went missing and when the UID was found. So I think you're right not to rule out based on head injury alone.
Here's the current ruleouts list (

Brenda Allen-Szabo 1949 California
Carol Arcuri 1939 Florida
Billie Hall 1960 Maryland
Wendy Huggy 1965 Florida
Patricia McGill 1941 Florida
