Would I still be able to get money back from a cashiers check I bought and send to someone who didn't send me?

Back in March 20, 2006, I bought a official bank check from my bank ( I found the carbon copy of it). I then sent the money to the person who was supposed to send me the item I purchased but I never got it. I was asked to make it payable to: Chris Robin/Efashion luxury. Now, I was introduced to this person/company by a Mia A who asked me to send the money there. I did. I'm beginning to suspect that she might be the person behind Chris Robin and had scammed me. The last I heard from her is that she was getting a divorce and moving back to her country. I googled her name and saw she has a company in the US still. I want to know if my bank can actually trace who cashed the check (from my copy) and if I can somehow get back my money. Please only advice me in a good way and not lecture me. Thanks.
