In a dramatic turn of events, federal agents have dismantled a staggering $770 million money laundering operation that was hiding in plain sight.

Now, the DEA and IRS tactical teams descended upon Martinez Auto Repair, a seemingly ordinary auto shop in Kansas City.

This raid marked the culmination of an eleven-month investigation into one of the largest financial networks supporting the Jalisco New Generation Cartel (CJNG) in the Midwest.

While the shop boasted a 4.7-star rating for its quick oil changes, it served as a critical node for laundering drug proceeds from 19 states.

How did this unassuming business become a hub for cartel activity?
