Residents in Grayson County are being warned to closely watch their mailboxes after another case of mail theft.
The sheriff's office says a resident who lives on FM 1753 in Denison had checks stolen out of their box.
The resident didn't realize it until the bank statement arrived.
Checks used to pay the bills had been written for more money and used at a Wal-Mart in Little Rock Arkansas.
They're still investigating this one.
