My sister and I watched a film set in the 90's in America, maybe somewhere like New Orleans (Louisiana, Alabama, some kind of place like that). The film is about a family whose daughter is kidnapped and murdered on the first day of her kidnapping, but the murderer states that she is still alive, it has a lot of court room and church based scenes, I can't remember any of the actresses or actors. In the end credits is a picture of a country lane where the girl was snatched from, and when the credits go up the song Amazing Grace is sung.
