This I totally believe. I know of families where Mama pulls the strings while people just think she's a nice Grandma. I bet she's a force to be reckoned with.Don't assume Rob pulled them into this. Dianne Ford is known to be a very powerful matriarchal figure in that shitshow of a family.
As for Lisi? Everyone is obviously wrong because Kathy met him once and he didn't do anything. And of course we all know criminals spend every waking moment doing criminal things.
