The Jackson County Sheriff's Office says it is investigating the possible source of scam calls related to its office and also warns citizens not to fall for the scam attempts.

The sheriff's office said it recently learned some citizens have received phone calls from a “Lieutenant Sullivan” and “Lieutenant Davis” in the warrant and citations unit of the sheriff's office, requesting money.

The sheriff's office does not have such a unit, it said, it urges citizens to not comply with any money demands.
