If the police have a failed lie detector test that would be just enough to charge you. However, in light to the closing of the DCS case and the obvious credibility problems with your stepdaughter's story, law enforcement would usually take a different approach.
Once you are acquitted, you can then attempt a lawsuit against the department. You would need to show four things in order to win a lawsuit for malicious prosecution:
(1) that the original case was terminated in favor of the plaintiff, (2) that the defendant played an active role in the original case,
(3) that the defendant did not have probable cause
or reasonable grounds to support the original case, and
(4) that the defendant initiated or continued the initial case with an improper purpose
Your first order of business is to hire the best criminal
defense lawyer you can. You must win the criminal case against you before anything else matters.
