While looking for articles on the Girls Home, I found this police blotter report from April 1981. Someone has reported four 15 year old runaways from the home, on April 4, 1981, who left in a red Buick. Linda would have been 15 then (turning 15 in August). Could she have been one of these girls?

Some further digging suggests that the child paired with her in the earlier articles was a slightly (1964) younger brother. He unfortunately passed away in 2001 in the Tampa area. Linda is not mentioned as surviving or predeceasing him in his obituary, but neither are their parents or various other relatives.
I’m no longer able to edit it, but several of my links are fluky above—the copy function on Newspapers was acting up. I’ll try to fix later on a proper computer.
