I can see how it could be an
innocent mistake.
Possibly...but the woman in that picture looks to be about the same age as Fred +/- 5 years. So, unless it was mislabeled from the original source, I'm not sure how you'd mistake her for his mother. Jeri's maybe...not Fred's. If she wasn't identified in the picture from the original source, then it was irresponsible to post that it was her.
