Sgt. Aguado is a cop played by John Capodice in Ace Ventura: Pet Detective. He is portrayed as a specific cop that Ace Ventura dislikes. Aguado constantly laughs at and ridicules Ace, though Ace constantly one ups and taunts him for being fat.
When Ace Ventura arrived at the Miami Police Station, Aguado began taunting him along with the other cops. He spotted a roach on the floor and stomped on it, mocking it as a "homicide" and asked Ventura how he plans to solve it. When he began stating facts Aguado attempted to strike him, but Ventura grabbed him and brought him to the dead roach, telling him to kiss and make up. After Roger Podacter was reported to have committed suicide, Aguado arrived at the scene of the crime along with Lois Einhorn/ Ray Finkle and numerous other cops. Later on, Ace Ventura came in with Melissa Robinson. Ventura suspected that Podactor was murdered and did not in fact commit suicide, but Einhorn said he needed evidence to back up his claim.
Aguado jokingly claimed he heard a toilet flush and somebody had lost a turtle, laughing along with the other cops. However, Ventura proved that Podactor's death was murder by revealing that the door was soundproof double pane glass. Aguado realized that Ventura was right, shortly afterwards Einhorn ordered him out.
