Find another way
You decide to do more research on the violent deaths you are accused of. On your computer, you search the database for these suspicious deaths, and you find something rather peculiar. It could be the piece of evidence to save your case.
The officials who found the bodies noted that they appeared to have bite marks not of a fox...but of something larger. Like a wolf. There is no way a fox could've done this.
Not only this, all of the victims were innocent, no bad track records, no evildoers, model citizens. You would never take the life of an innocent, it's in your code. Instead your normal type are murderers, rapist, and rich people that take advantage of the poor.
It all checks out.
