A Texas man has been convicted of ripping people off by installing credit card skimmers on gas pumps throughout west Michigan. The U.S. Attorney’s office in Grand Rapids tells us 44-year-old Antonio Perez-Martinez, of Austin, was found guilty Monday of credit account fraud, and aggravated identity theft after a four-day jury trial. The office says he was the leader of a conspiracy that at times involved more than a dozen suspects who allegedly got compromised credit-account data online, encoded it on to cards, and then used the cloned cars to buy gift cards in bulk. During the summer of 2015, Perez-Martinez then moved on to the gas pump skimmers. He’s one of seven people now convicted in the case, and he could get up to 30 years in prison.
