The U.S. Customs and Border Patrol Chicago Field Office, which handles operations throughout most of the Midwest, seized six shipments from the Louisville airport containing 2,909 fake IDs and more than 3,000 blank card stocks.

a tweet by the CPB Chicago said the fake ID’s were found at the Louisville mail facility.

Investigators say one shipment was heading to a convicted child rapist in New York who reportedly uses the IDs and alcohol to entice minors.

Officers fear the other parcels may be linked to human smugglers or traffickers.

The items were turned over to the CBP Fraudulent Document Analysis Unit.
