The $100 bills that showed up in the cash register at a Walmart in western Pa. were “poor quality and appeared to be printed on typical printer paper,” according to the criminal complaint in the case.

The question was how they got there.

As KDKA-TV in Pittsburgh reports, the bogus bucks were traced to two transactions with the same Walmart checkout employee. Both were made by the same customer, as well.

All told, the Walmart manager in Gibsonia, Pa., reported to police the store had received a total of $1,000 in badly faked $100 bills on Dec. 23.

This, after the arrested suspect in the case, Dexter Delean, was caught on surveillance tape making two separate transactions to the same employee, Lasania Mattis, KDKA reports.

It turns out the pair are a couple and police are now calling their actions a “counterfeit money scheme.”

Police arrested Delean after he returned to the Walmart on Jan. 3, and police say he admitted to paying Walmart $400 total in counterfeit money.

Moreover, police say Delean implicated Lasania Mattis in all of the counterfeit money schemes. However, she has denied this to police, KDKA says.

But Delean told police that he and Mattis were dating and lived together. The vehicle Delean was using was registered to Mattis, as well.

Both Delean and Mattis have been charged with two counts of forgery, two counts of theft by deception and one count of criminal conspiracy by forgery in Allegheny County.

They were arraigned on Saturday at 3 a.m. and will face a preliminary hearing on Jan. 15, KDKA reports.
