but Dexter later begins to doubt the authenticity of Miguel's friendship when he learns Miguel used exactly the same language he used in a talk between them in a talk with Rita about trust. Dexter's suspicions are confirmed when he examines the shirt Miguel gave him after the murder of Freebo. The blood on the shirt is in fact cow blood, and Dexter realizes that Miguel has been manipulating him all along. After a game of one-upmanship with regard to Ellen Wolf's murder case, with Miguel threatening to expose Debra Morgan's relationship with the CI Anton and use his position as ADA to make trouble for Dexter, Dexter decides to kill Miguel using the MO (Modus Operandi) of a sought-for killer, just as LaGuerta discovers Miguel killed Ellen. When Miguel discovers that LaGuerta is investigating him, he plans to kill her. However, Dexter discovers what Miguel is planning, traps him at LaGuerta's house when Prado goes there to kill her, and kills Miguel by garroting him, but not before telling him that he killed his brother. The entire city of Miami mourns the passing of Miguel Prado, a hero to all, and so the City Council votes to name the city's main freeway interchange after Miguel. This greatly upsets LaGuerta, who is ready to accuse Miguel of murdering Ellen Wolf. Dexter is able to convince her that doing so would only hurt Miguel's family and the Cuban Community, and there is a high chance that nothing could be proven, so she drops it. It was later discovered through Miguel's brother, Ramon, that he also lied about the story of defending his family from their abusive father where it was, in fact, Ramon who did it.
