It started with a report of items from a freight train, being sold online.
Sitka, a high-end hunting apparel company, said about 100 pairs of hunting boots, valued at $40,000 had been stolen in Chicago.
The company said it found Facebook Marketplace and eBay listings for the products.
Investigators tracked the seller to Palos Heights, where they found boxes of shoes and appliances.
