A new NamUs casefile was created yesterday for Sallie Belle Maxine Signani of Renton WA https://www.findthemissing.org/en/cases/14018/4 A bit of googling led me to this Genealogy site. http://www.feldenzer.com/gard/dat2.html She is listed here as Sallie Belle Maxine Gard. She was born on 24-Aug-1940 in Enumclaw, WA. Her death is listed as "Abt Jun 1973", so this appears to be the same woman. It indicates that she had seven children, and was the daughter of Rodney Alvera Gard and Dessie Isabelle McDaniel. I couldn't find any photos of Sallie from the time that she disappeared (at the age of 32). However, here is a photo of her at the age of about 15-16 from the 1956 Enumclaw High School yearbook.
