An indictment is being returned by a federal grand jury in Providence against a Pawtucket man in an elder fraud case.  The U.S. Justice Department says Shawn Whitfield is charged with ten counts of mail fraud and 29 counts of wire fraud.  He is accused of participating in a telemarketing lottery scam based in Jamaica that targeted U.S. citizens, mostly seniors.  Whitfield is among more than 250 defendants worldwide named in criminal, civil and forfeiture fraud cases following an announcement of a coordinated sweep of elder fraud cases in February by U.S. Attorney General Jeff Sessions.
