Bookfilter: Trying to remember the name of this crime novel about a 17 year old girl who poisoned and eventually killed her talented sister for attention.

What I can remember is that the female 17 year old tries to develop a relationship with the male investigator, telling him that she's eighteen years old.
At the end, when they begin to suspect her, the female investigator wears a wire and elicits a confession, which they later realize is inadmissible because she's not 18.
She goes to jail, and in the end I think they discover that the mother knew all along that her daughter was poisoning her other daughter.
What is this book? Thanks!
