BARGERSVILLE, Ind. -- Federal investigators are looking into another case of counterfeit cash in Johnson County, where one family claims their bank gave them a phony $100 bill.

Jeremy McLaughlin said he cashed a work check at Heartland Bank on Tuesday. But when he went to get a money order at a local gas station, he was told that one of his $100 bills was fake, Call 6's Rafael Sanchez reported.

The bank turned the case over the U.S. Secret Service.

"I'm aggravated. You feel secure when you go to the bank to cash a check," said the father of four. "$100 to us is like $1,000."

A bank spokesman said that staff members get extensive training in spotting counterfeit cash.

"It's our main obligation to pull counterfeit money out of circulation, not pass it out," said Heartland Bank Senior Vice President Trent McWilliams.

The case marks the second time in three months that a phony $100 bill has shown up in Bargersville.

Andy Cecere, an assistant special agent in charge with the Secret Service, said that the agency has seen an increase in fake $5 and $100 bills because they share similar security features.

He said while it's possible for a bank to accidentally pass fake money, it's very rare.

McLaughlin's fiancée said the family just wants the incident cleared up.

"In all honesty, we are the victims here, and we shouldn't be," said Stephanie Hammons.

McWilliams said Heartland Bank will wait for the report from the Secret Service before determining its next move.
