I am attorney of the accused in Twelve Angry Men, how do I convince the jury that the accused is innocent?

We have to do a journal entry where we write the closing remarks for the case that was tried in Twelve Angry Men. In other words, we have to pretend that we are the attorney defending the accused. We are appealing to the jury, trying to convince the, that the accused is in fact innocent. What would;d be some evidence to Tell the jurors to show them that the accused is indeed Innocent not guilty.
