since it appears all the fraud is coming from Chase payment methods, contact Chase, elevate your levels of concern, ask if they will provide a letter indemnification so you can return the funds. if they do, return the funds and close the account. if they won't, release the funds and close the account.
and if you caught that the names did not match when you opened the account, why was the deposit allowed? Seems there needs to be some training in your branches.
