Movie where Girl turn out to be diabolical

A boy finds a girl attractive (both of them in their post teen approx.). And she happen to be  from a wealthy family. Some one in her family gets killed in a car accident. The boys get to be blamed. There is a sex scene at her house (when dad is out). Later the boy finds out that it was the girl all along who was killing her own family. And she tries to put the blame on her boy friend. She some way learn to tamper with the car brakes or the engine(in process of killing her own father). This is some movie which i have seen long back. Couldn’t remember the tittle or the actress in his film. If any of you could recognize. Please let me know. All I know is, this is not a recent one, at-least way before 2000’s.

Thanks.

  1. I really shouldn’t care, but…why would this be marked “solved” when it was never confirmed by the OP on either occasion?

  2. I marked it “solved” just so I could remember to distinguish it from the other thread, which I consider the “live” one, if it ever came up again. I’ll change it to “administrative,” which is the catch-all category.

Got something to say?
