I saw the case involving the seemingly spooky church lady who killed a woman in her church and walked out and went and got her hair done.

I think justice was served , Mary Jane Fonder seemed odd , the gun was hers , powder residue was found in her car .

But the one thing that is bothering me is , no one ever explained why there was no powder residue on her wig when she left it there mistakenly after getting her hair cut .

This piece of evidence was introduced at the beginning of the show and not included at all in the police Officers final summary of the case at the end.

Logically she could have murdered the woman with the wig off , but I don't think she was quite that complex . It is not a big deal, but I would have liked to hear the police officers opinion on it.
