I'm not going to give my sources on this out of their own protections, but when he/she and I talked, they told me that Mindi told her/him about a meth lab She had in her mother's basement. This was at the time when Dave Dietrich (Fern's Husband and Michael Newbold's step dad) was still in the Quincy Police Department.
So if Fern/Dave ever wants to get on your ass about things that are against the law, or bitches about your background/criminal record; just let them know, that you know, about harboring her daughter's meth lab in their house's basement WHILE there was a source of "law enforcement" living there.
Why believe this person?
1. They didn't call Dave by his name, meaning it's no discrimination against Dave himself, just said "She told me she had a meth lab in the basement when she was staying there and her mother was married to a cop!"
2. He/she has always kept their word.
