A fellow’s wife went missing and being that ever

A fellow’s wife went missing and being that everyone knew that he and his wife were in a big fight he was accused of murdering her and disposing of the body. When witness after witness came to the stand testifying to all sorts of horrible threats that the accused threatened his wife and things were looking quite dim for the accused the man’s lawyer got up to the stand.
“Ladies and Gentleman of the jury I have something quite exciting to tell you, if you would all please direct your attention towards the door behind me on my left you will see the supposedly dead women walk in on her own two feet.”
There was a loud murmuring in the courtroom as all eyes turned towards the door. “Ladies and Gentleman” said the lawyer after a few seconds of anxious waiting, “To be honest with you, Nobody is going to be walking through the door, however from the fact that your eyes all turned towards the door it is quite obvious that you are not sure beyond the shadow of a doubt about my client’s guilt.”
To the lawyer’s great surprise, the jury decided that the man was guilty.
“But how could you say that he is guilty? Didn’t I prove it to you?” Questioned the lawyer.
“It is true that we all turned towards the door,” one old lady explained, “but there was person who didn’t.”
“Who’s that?” Questioned the indignant lawyer.
“Your client.” Came the reply.
