So I saw this article about Dale Pearl Smith‘s disappearance and it does not really provide any more info than I had before, other than the mention of Westmoreland Road. I have updated Dale’s case with that bit.
The thing is, though… it says she was last seen on Mother’s Day, May 11, 1987. But I looked it up and Mother’s Day was on May 10 that year.
There is no explanation for the discrepancy. Was it a typo? Or maybe there was a scheduling issue and Dale and her daughter decided to meet for Mother’s Day the day after instead of the day of? I have no idea.
I’ve got her disappearance down as May 10 but there’s a good chance it’s May 11. I have no clue.
If anyone who knows something about the case, such as one of Dale’s relatives, finds this blog I’d love to have this matter cleared up so I will know I have the correct date.

I think you are correct – May 10th. She has a grave marker and it’s dated May 10, 1987

Perhaps May 11 was the date she was reported missing. Many times they make you want 24 hours or longer for an adult. Especially back then.
