The Grant County sheriff’s department says it has received reports of mail thefts happening in areas south of Mattawa. According to the department’s Facebook page mail thefts happen regularly across Grant County, and they offer some tips to protect your mail from thieves. Use the letter slots inside your Post Office to send mail or hand it to a letter carrier. Don’t leave it in the mailbox to be picked up. Also pick up your mail promptly after delivery. And be sure to let the post office know when you’ll be out of town so they can hold your mail.
