Mark in boonville,
Bummer for all involved!
Here are some thoughts I would have if it happened to me:
I would consider talking to your bank to see if they recommend changing your checking account number and/or putting a security PIN on the account. Because now someone has a copy of all your checking account info...plus a sample of either your signature or your wife's.
Also wonder if it would be good to do a stop-payment on those checks too - even though it probably cost at least $25 bucks each. On TV they say criminals can somehow "wash" your checks and then put themselves in as the payee (plus write it for a higher dollar amount).
