They did and that's why they caught her.
Kudos to you for doing the math, though.
I was still trying to figure out if every woman gave birth at 13 in that family.
Gotta read the whole story friend. According to the story the SSA had nothing to do with locoming in to it. she was discovered this way:
“According to a report by WHTM-TV in Harrisburg, Delahay’s body had been found by two women who had been inspecting the Kralltown Road home because they were interested in buying it from the bank after it foreclosed. The potential buyers had told police they were looking around in an outbuilding when they discovered remains wrapped in trash bags and under blankets in a white chest freezer, the TV station reported.”
It makes sense,
Grandmother was 97 when she died so Her Granddaughter was around 46 then (depending on the Month).
So 46 years from her birth Grandma was 51 years old, when this human debris was born. So Mama had to be mother sometime in her what 20’s 30’s at the latest.
