Oh, shoot — this is one of those “really gotta keep reading” threads. Sorry about my previous post.
I think that when your Creepy Behavior Alarm goes off, you really need to heed it. Not convict someone right away, but stay alert until subsequent behavior quells your first instinct. Which does occasionally happen.
But in this case, your sense of foreboding is only getting worse.
A girl with whom I went to high school was sexually molested by her father, it was in the papers once he was convicted. She was a freshman when we were seniors, and I recall her being particularly clingy with one of my classmates. To the point where it really stood out - I was surprised that she was apparently “slutty”, because I’d known her (slightly) for a couple of years. Her parents owned a business located next door to the fast-food restaurant where I worked. So I’d seen her Mom and Dad on several occasions, and remembered her when she was just a perky 12-yr-old.
And I’ll tell you what – her Dad was exceedingly creepy and secretive, anti-social. Her Mom was withdrawn and strange. Although they bought food from us occasionally, they refused all friendly overtures. To the point of not even replying to innocuous remarks about the weather. You’d think a neighboring business would want to be congenial. I never suspected he was molesting his daughter, though; people have a right to be weird, it’s hardly criminal.
Given your niece’s recent forays into revealing clothing, your BIL’s and SIL’s strangeness as documented here, the 12-yr-old’s crotch-grabbing incident, and particularly your gut instincts, I think you have every reason to be alarmed.
I don’t know what you should DO about it. I’m one who DOES call “the authorities” as a matter of course; I tend to believe that they can be trusted to do their jobs. In your shoes, I would call CPS (I don’t buy that Mondale Act busines, my MIL was a social worker for 20+ years & they worked hard to keep families intact; it was exceedingly difficult to justify removing children).
There’s also the Center for Missing and Exploited Children, started by that John Walsh guy whose kid was murdered - maybe they would have the right resources, or could direct you to them.
