A former vice cop, Antonio had a rocky start with Sargent Hank Voight. In Chicago Fire Antonio led the arrest of Voight, then after he was released became a detective in his unit. Antonio is an honest cop, he plays by the rules no matter what. Voight is quite the opposite, and Antonio has a problem with that, but when it comes to finding his son he will do whatever in necessary to get him back. In both seasons 2 and 3 Antonio is approached about taking over the unit, by trading info to get Voight in jail. Antonio turned down both offers in order to stay loyal to his Sergeant.
During his rookie years, Antonio had a partner, Sean Patterson. Sean had mistakenly filed double overtime pay, a minor infraction. However, Gradishar of Internal Affairs (I.A.) had Sean fired and took away his pension. The shame caused him to commit suicide a year later, leaving behind a wife and kids. Antonio has never forgiven Gradishar for using Sean as her way of climbing the corporate ladder.

In the first few episodes of season four Antonio is slowly becoming tired of all the depressing matters the team deals with daily, stating "I've seen too much of this."

In episode eight Antonio officially left the Intelligence Unit to become the Chief Investigator with the state's attorney's office.
