I'm Lucy, and I'd be happy to answer your questions today. I'm sorry to hear about your situation.
What your wife did was slander, malicious prosecution, filing a false police report and hacking, all of which are illegal. The first two are civil offenses, although you can only sue for malicious prosecution after any charges against you are dropped (or not filed). You may also have a claim for intentional infliction of emotional distress if this is part of an ongoing pattern of behavior. Filing a false report and hacking are crimes. If she actually put the bruises ON your child, then that's child abuse, and you can file a police report for all of that.
The Fifth Amendment says that a person cannot be compelled to testify against himself by police or a court of law. If police asked you questions without informing you of the right to remain silent first, that's a violation. But your ex-wife can't violate your Fifth Amendment rights if she's not in law enforcement. It would all fall under defamation of character and intentional infliction of emotional distress, both of which carry punitive damages. Malicious prosecution also carries punitive damages.
If you have any questions or concerns about what I've written, please reply so that I may address them. If I did not address the specific thing that you wanted to know, it may not have come across clearly to me, so please restate that question. It's important to me that you are 100% satisfied with the service I provide. Thank you.
