Earlier this week, Chad and Amanda Reasoner found mysterious transactions had removed money from their bank account.

There were four transactions on a Capitol Federal debit card totaling $633, the Lawrence couple found. On Thursday they noticed their account showed another transaction, upping the total to $743. Purchases were for clothes and electronic items, Chad Reasoner said.

“I canceled it (the card) after I saw the first one, but then the others appeared,” he said.

Even more mysteriously, a merchant’s invoice was mailed to Amanda Reasoner, apparently for verification purposes, at the couple’s Lawrence address. It showed the merchandise ordered in one of the transactions was shipped to an address in Fort Worth, Texas. “Somehow they got more than just the card number, they also got my wife’s name and address,” Chad Reasoner said.

The Reasoners are victims of a security breach publicized last month at Heartland Payment Systems in Princeton, N.J. Hackers gained access to credit and debit card information from millions of transactions. Heartland processes the transactions.

Capital Federal sent out letters a few days ago to customers that cards were going to be canceled and new ones issued, Chad Reasoner said.

“We didn’t think anything about it,” he said.

On its Web site, Heartland states it is working with federal law enforcement agencies in investigating the breach. Heartland also states that any fraudulent transactions related to this incident won’t be charged back to the cardholder. Nevertheless, the money is gone, since it involved a debit card instead of a credit card.

Reasoner is contacting the merchants, trying to get the money back. Capital Federal also is working to get the money returned, but it may take a few weeks, Reasoner said. One merchant said it would need a subpoena to return the money, he said. He has also passed on the information about the Fort Worth address to Heartland.

“We’re just working through this,” he said. “I hope this person is leaving a bigger trail than they should.”
