Notice!

Anyone knowing of a bitter, soon-to-be ex-wife out to get revenge on her cheating, good-for-nothing, stole-the-best-years-of-her-life, scumbag of a husband by selling his relatively new, apple-of-his-eye, in-great-condition motor vehicle for dirt cheap please pass her information on to me.
I'm in desperate need to be mobile again.

Who is guilty?

Wife is dreaming in the middle of the night and suddenly shouts: "Up! Quick! My husband is back."
Man gets up, jumps out of the window, hurts himself, and then realizes: Damn, I am the husband!"
Who is guilty in this situation?
