I am trying to find a movie where a female lawyer takes a case defending a man accuses of killing his second wife.He was also accused but found not guilty of killing his first wife.The lawyer finds him guilty and tries to help convict him without losing her license.he gets off and then tries to kill her but she was expecting him and made sure she got DNA by scratching him ,hair etc. In a twist she ends up killing him.
I know all the movie but for the life of me can't find the tittle

Sounds like Guilty as Sin (http://en.wikipedia.org/wiki/Guilty_as_Sin)

THANK YOU! This was driving me crazy!<3

You're welcome.
