Scammers in North Texas are preying on unsuspecting victims with a strategy known as the ‘bank impostor’ scam, conning people out of thousands of dollars. Two residents, Pastor Oscar Epps and Sam Heller, found themselves ensnared by fraudulent calls that appeared to come from their respective banks. Epps, from the Cedar Hill vicinity, and Heller, a Roanoke area local, experienced near-identical scams last Tuesday when their trust in caller ID was exploited by thieves.
