My question involves criminal law for the state of: Wisconsin
In May 2014, a Harley Davidson jacket that had been given to me as a gift went missing from my apartment. There was one other item that was also missing. The jacket was given to me by my boyfriend at the time (I had filed for divorce, but it was not yet final), and the other item belonged to my boyfriend. I suspected but never had proof that my ex-husband was the one who took it... until now. My daughter knew about the jacket going missing and just two days ago, she texted me a photo of my ex's current girlfriend wearing the same jacket with the remark: I think Kim is wearing your jacket. Isn't this the one that went missing?
Unfortunately, that jacket is a HD staple and is still available in most HD stores and online. I am checking to see if there is a way from the serial numbers in the jacket to determine from which HD store it was sold. Mine came from a store in Orlando, FL where my boyfriend bought it while on vacation, and we live in Wisconsin. If I can prove that "her" jacket came from Florida, and he claims to have bought it in Wisconsin, do I have a case for theft? I confronted my ex about the jacket and he would not discuss it with me and was instead more interested in finding my 13 year old daughter to scream at her for texting me the photo. He claims that he purchased the jacket for his ex about two months ago and mentioned to my daughter that he knew mine had been missing for two years. I NEVER SAID A WORD TO HIM ABOUT THE JACKET, so how would he know it was missing for two years? And, I replaced it with an identical one shortly after it was stolen and have worn it in front of him on numerous occasions. The first time I wore the replacement in front of him after the original went missing, he looked like he'd seen a ghost. I was 99% sure at that point that he had stolen it. Do I have proof enough to pursue this criminally?

I'M NOT IN ANY WAY ADVOCATING OR ENDORSING "alternative" RECOVERY METHODS!!!!!!!
