The Cass County Sheriff’s Office is reminding residents in the County not to give out their personal information to unfamiliar callers and/or in response to mail solicitations. Giving out that information may lead to identity theft. The Sheriff’s Office says you should never give out your personal information over the phone, and never send your personal information to any requestor that you do not know and trust. That includes bank information, credit information, social security numbers, and family information. They advise you not to respond to any mailings of doubtful origin, and to hang up on callers requesting personal information.
