I have had some pretty strange and unrelated things come up during a search- but that does seem far-fetched.
The whole family is a nest of pathological liars. Amazing that her dad was a police officer for years and her mother is an RN, seems those are two occupations that expect people to be truthful.
No one is going to disagree with you, that this is one messed up family.
All I can say is that I have friends whose daughter was a pathological liar. She told so many lies that when she finally told people that she was having sex with an older neighbor boy (since she was 11 or 12), no one believed her. So, she told them it was her father.
The school reported it and the parents were hauled into court and refused to plead guilty to something they didn’t do. Eventually, it was all straightened out, but the daughter put the family through hell. She continued to put everyone close to through hell and still does.
I have known quite a few crazy nurses (my mother-in-law, for one).
I almost hate to admit this but my grandpa was a police officer in a major city for 37 years and it is not unusual for cops to cover for each other and sometimes for family members.
My husband's ex-wife is a nurse and she is the laziest, meanest, and biggest liar I have ever personally met. Not all nurses are kind, gentle, or dedicated to doing good for other people.
