I cashed a check through the mobile checking app of my bank, Bank of America, on XXXX XXXX of 2015. This was a check written to me, for the sum of {$300.00}. The app recommended i keep the physical check for up to 30 days before destroying it, so I put the check into my filing cabinet. 

At some point my ex-roommate went into the filing cabinet and stole that check ( along with other things ). Unfortunately, i did not notice the check missing. A month after I moved, on XXXX XXXX, 2015, he cashed the check at his bank. After the check cleared, the person who wrote the check to me, noticed the funds deducted from her account, and mentioned it to me. I explained that I had cashed the check back in XX/XX/XXXX. She found that the check had been actually cashed twice, the second time, fraudulently. She called the bank. They investigated the matter, and decided to take the funds from my account. 

After many calls, explaining the situation, the bank has not put the money back into my bank account, ( and i suppose, not to take it from my ex-roommate, who stole the check ). The person who wrote the check and I, even made a 3-way call with the bank, explaining the situation, yet it did not make a difference in the banks decision. 

I have since started a complaint with the XXXX Police Department, who is regarding this as a criminal investigation, against my ex-roommate.
