San Antonio — Authorities said Wednesday that in breaking up a San Antonio-based smuggling ring that funneled guns to the Zetas drug cartel across the border from Eagle Pass and Del Rio, they seized 203 weapons but were unable to stop every shipment.

Officers said they confiscated mostly assault-style rifles and one .50-caliber Barrett sniper rifle in five separate shipments between May and August 2010.

But they said they also learned that three other shipments with an unknown number of weapons made it to Mexico before they started investigating.
