[Sweetheart]

...that I have seen on lifetime tv? some of things that happen in the movie were the husband murdered his wife and the family has a hard time proving it when he killed her he used a dumbbell and then wrapped her body in the carpet and throw her body on the side of the highway. he used to abuse her a lot, his family didn't believe he killed his wife and only realize it when their bedroom lights up the blood in the room from it being searched by crime scene investigators, when the sister has to identify the body she recognizes a piece of jewelry that she gave to her during the trial the husband tries to slander his dead wife by saying she abuse drugs but it is shown that she only use certain ones for medical purposes because he broke teeth by abusing her i remember what helped to prove him guilty was they showed a video of her playing with the baby that they had together to show what a good person she was if anyone can name this movie i will be very grateful and award top answer.
