Now go get a lawyer.
Put NOTHING of a threatening nature in any form of writing or voicemail. Hell, write nothing that doesn't document that you are in the right for that matter. Consider everything you do as possible evidence in a future court hearing and act accordingly.
Good luck & don't lose hope.
