He: My wife has been missing since three o’clock, you have to help me find her.
Police: Okay, why did you kill her and where did you put her body?

Police: Did you kill her after an argument? Did she have a big insurance policy? Are you fooling around with some other woman?

Police: We will, as soon as you tell us where she is.

Oh for goodness sakes.....that was stupid.
