Michael Rock Victim of Bank Fraud

***UPDATE*** 9:12am Just found out that the check was cashed at a credit union in Boston. Also...the organization is sending me a new check.

I hosted an event last month for a local organization.  The organization told me they mailed the check here to Fun 107, but I never received it. 

After weeks of going back and forth with the organization, they finally sent me a copy of the check that was ALREADY CASHED!  Someone stole the check, forged my name, and cashed it!  Below is "Exhibit A".

I feel so violated. So, now I have to figure out what to do next. Do I go to the bank? Will I ever get paid? Does anyone recognize this hand writing??? Should I offer amnesty if the person comes forward? So many questions.
