I cashed a fraudulent check and now the bank is making me pay back all the money! (Ohio) : legaladvice

I was selling an item($800) on Craigslist and a buyer wanted to pay via check. He sent me a check in the mail but it was for much more than what the item was worth($3,000). He said it was a mistake that his assistant made and to wire me back $2000 and keep an extra $200 for my trouble and he would send a shipping company to come pick up my item.

I cashed the check via mobile deposit so a teller didn't get to actually hold the check or anything but it cleared my bank in one business day and I wired him $2,000. He said he would be sending a shipping company out within the next couple days. I hadn't heard from him in a week so I thought the shipping company messed up, whatever. Then I get a call from my bank saying the check deposited bounced and they took the whole $3,000 back!

They informed me I got scammed via a check scam and there was nothing they could do. They said I'm responsible for paying them back when all I did was cash a check! How is it my fault that the bank cleared the entire amount of a $3,000 check without even verifying the funds?! This is insane!
