Watched a movie last year.have searched everywhere and had no luck .all I remember was it loosley based on a true story ..a guy comes out of prison and lives with his girlfriend..he gets abusive with her .but only when there alone in the house ..she ends up having enough one night and kills him while his asleep .can’t remember if she shoots him or hits him with a hammer .then she rolls him in a carpet and buries him in the garden ..then she reports him as missing but it ends with police digging up the garden ….she goes to court for the murder but doesn’t get done for manslaughter ……
