According to a statement from Captain Jeff Medlin, felony warrants have been issued for David and Travis Twitty.
New information indicates the scam has been going on since 1997 and Methodist churches in Georgia were targeted.
"I have been contacting as many victims as possible to try and convince them to prosecute our suspects," Captain Medlin said.
Since the investigation began in Moore County, Medlin said he has talked to victims from Alamance, Chatham, Durham, Harnett, Lee, Montgomery, Moore, Randolph, Richmond and Wake counties.
Initially, the scam was thought to be contained to Chatham, Lee and Moore counties. Investigators said they did not have filed reports to refer to, but the father and son had allegedly visited many churches.
The duo tells churches they have a family member who was killed or injured in an accident. The church then gives the men large amounts of money to help the alleged victims.
The men are described as black males with dark skin and long dread locks. David Twitty is between 30 and 40 years old, between 5'11" amd 6' tall and 170-180 pounds. Travis is about 16 or 17 years old, between 5' and 5'9" tall and weighs between 140 and 150 pounds.
They have been seen in a red Jeep Cherokee with South Carolina tag AKA 475.
No one has been injured in the incidents, but authorities want to warn people and hopefully prevent further scams.
