Trying to find the name of a horror movie. Help!

The movie I am looking for starts with young woman trying to find a job in a newspaper. Then she starts woking for an elderly couple in a big house. She babysits the old man who is paralyzed and he can’t talk. Later on the babysitter finds out that the old woman is doing some things so the man can’t talk. There was also mentioned something about people being hanged to death on some three in the yard of the house. Can somebody help me find the movie ? I have watched it before 5 or 6 years and theese are the only things I remember.
