[TOMT] [MOVIE] Terrible wife

So this movie I think was a true story? But either way, it was about this guy who grew up with parents who own casinos/hotels in vegas I think. When he was older, he married a stripper that has a daughter. The wife's brothers killed his mother and attempted to murder the daughter. The detail I remembered is that he has a batmobile (as in the actual car), the wife is in on the murder (she's the one who ordered it) and the movie ends with the wife wearing some pearls.

Please help me find it, Thank you 🙇
