After two men were allegedly selling items bought with other people’s credit cards at yard sales, police are warning buyers to beware. “When you’re buying at a yard sale, it’s kind of like buying a product with no guarantee,” Oakwood Police Sgt. Danny Sridej said. Jacob Lawrence Barnes, 22 and Ross Randolph Sweat, 19, were charged last month with multiple counts of financial transaction card theft, credit card fraud, attempted identity theft and entering auto.
