Monica Fuentes is a U.S. Customs agent who worked undercover as an assistant for drug lord and dealer Carter Verone.
2 Fast 2 Furious
Fuentes has been working undercover for nearly a year when Brian O'Conner and Roman Pearce are brought in. She develops feelings for Brian, but earns Roman's mistrust. Monica later warns Brian that after a mission Verone has assigned them, he intends to kill them. She blows her cover by telling Brian about the airstrip, being the one person Verone notified about it. She is then taken captive aboard his boat, but Brian and Roman jump their Camaro onto the boat, allowing Brian to shoot Verone, injuring his arm, while Monica holds him at gunpoint. After taking Verone into custody, she forces Roman to admit he trusts her now, and says goodbye, giving Brian a meaningful look as she walks away.
In the post-credits scene of Fast Five, Luke Hobbs receives a file from Monica regarding a robbery, in which Leticia's photograph is attached, suggesting she may in fact be alive.
