Antonio

Antonio was one of the operatives of Mexican crime lord Hector Salazar working inside the US during Day 3.

Day 3
When Kyle Singer tried to escape from David Gomez at the Los Feliz Mall, Antonio picked up Gomez in his pickup truck to give chase. When Singer's girlfriend, Linda made him pull over to let her out, the terrorists caught up to them. While Gomez grabbed Singer, Antonio caught Linda.

When they got back to the warehouse, a third accomplice hosed Antonio and Gomez down to protect them from being contaminated with the Cordilla virus.

A few minutes after hosing down, Antonio brought coffee for Gomez, the third accomplice, and himself.

Antonio, Gomez, and the third accomplice were killed when CTU agents stormed the hiding place and rescued the two teenagers.
