An ex-convict who was head of the Locos gang in Miami, he had a history of "making people disappear." During a face-off with Brother Sam, he has an unforeseen run-in with Dexter Morgan, which leads to his demise.
Julio is a large, muscled Latino man with multiple tattoos running along his upper arms, chest and neck. He keeps his hair short, practically bald, but fashions himself with a goatee. He also has distinct tattoos on his eyelids and a mole just under his left eye.
Julio is a killer, and very direct when taking care of business. He runs his gang like a tyrant, as they torment locals in Miami. If someone dares to stand up to him or his gang, he vanishes. This was the unfortunate case for one Hector Nunez, a barber shop owner.
Brother Sam is confronted at his body shop by Julio regarding one of Sam's workers, Nick. When Dexter disarms and beats up one of his gang members, Julio pulls out a gun to make himself feel more powerful and dangerous. He backs down, however, when Dexter proves that he works with the police.
When Julio ends up on Dexter's table in Hector's barber shop, he's left to bare insults and threats that his gang will kill Dexter for this. He's not given a lot of time to speak his mind so a confession of his killing of Hector is put to rest just as quickly as Dexter slashes his neck.
Nick, a body shop mechanic under the employ of ex-convict turned man of the cloth, Brother Sam, begins to miss work. Sam, who knows of Nick's addiction to drugs, goes to his house in order to intervene...only to be shot at by Nick. This forces Sam to knock Nick out, after which he carries Nick to his car and heads back to his shop.
Dexter, who is tailing Sam (as a potential victim) thinks that he killed Nick, and follows him back to the body shop. Dexter ends up encountering Sam and ultimately Nick, who is unharmed, smoking in the garage. This puts to rest Dexter's suspicion that Sam is still a killer.
While Dexter is still at the shop, a car rolls up with three men inside. Julio, the leader of Locos, a local gang, approaches Sam looking for Nick. Sam tells them to leave as it is private property, but they refuse.
Dexter approaches, willing to aide Sam. He does this by quickly disarming and grounding one of Julio's assaulting thugs...to which Julio takes notice with a bit of trepidation at just how quickly it happened. To make sure that he doesn't lose the upper hand in this scenario, Julio pulls out a handgun and aims it at Sam. He says that he'll leave, but only with Nick in tow
Sam stands strong and tells Julio he's not afraid to die, and begins to quote a religious saying. Not knowing if Sam is serious about dying or if he's just crazy, Julio debates in his mind whether or not to shoot Sam.
Dexter, not willing to take any chances, flashes his forensics badge and informs Julio that if either Sam or himself end up dead the whole department will be after them. At the request of one of his thugs, Julio decides to leave, but not without threatening Sam to avoid crossing him like the last guy who did. He reminds Sam of Hector Nunez and how his body was never found. Dexter takes note to investigate the claim.
Later, Dexter pulls Julio's file and learns that Hector Nunez went missing about six months back, after having dealt with a local gang. Considering the testimony from Hector himself, this removes the usual investigative process and Dexter goes straight for the kill. At some point, he sedates and brings Julio back to the barber shop that Hector owned, where a few gunshots were left piercing a mirror.
Julio threatens Dexter with his life by the hands of his fellow gang members, but Dexter simply deduces what happened to Hector. Before once again having to hear a threat about Julio's boys, Dexter stuffs a piece of tissue in his mouth. He tells Julio that he will make it quick because he has a more important ritual to attend to, referring to Harrison's bath and bedtime story. Dexter lectures Julio for a moment before slashing his neck, killing him instantly. Dexter, after killing Julio says, "...monsters don't get to live happily ever after."
