NORTH AUGUSTA, S.C.- Someone's calling homes pretending to be a Richmond County investigator and you could be their next target.

It's already happened to at least two women in a week.

NBC Augusta 26 News talked exclusively with one North Augusta couple who was targeted.

The couple who wishes to remain anonymous says Wednesday a man called and told them their numbers were given during a double-murder investigation and said they needed to come down and give a statement in person.

When they refused, they say he became even more persistent.

“The man said well what we'll do is take a marked Richmond County patrol car and we will pick you up."

The couple immediately hung up and called North Augusta Public Safety to tell officers what happened.

That's when they found out they weren't the only one's being targeted.

“They said someone had called earlier and had received very much the same call."

NBC Augusta 26 News took their information to Richmond County investigator Sgt. Calvin Chew.

He says something like that would never happen in their department.

"If we're investigating a double homicide, we're not just going to call somebody who's a possible suspect and say 'hey we need you to come down here and talk to us,'" said Sgt. Chew.

Sgt. Chew also says any investigator would give some type of identification, something this caller refused to do.

"That shows a red flag right there. If they refuse to give any information as far as name, a contact or anything like that then something is going on and you need to contact your local law enforcement agency," said Sgt. Chew.

And that's exactly what this North Augusta couple did.

Their quick thinking saved them from becoming victims.

NBC Augusta 26 News spoke with North Augusta Public Safety.

They say they are investigating this case.

They do know the caller was using a cell phone with a 706 area code.

North Augusta investigators believe the caller could be targeting the elderly.

Richmond County investigators are also looking into this possible scam.

Again, if you have received a call from someone who claims to be a Richmond County investigator, make sure you ask for their identification, but don't give out your information.

Then, alert your local law enforcement agency.
