Joseph Cepeda is one of Dexter Morgan's many victims killed prior to Season 1. His body is recovered along with at least 13 others and brought into an air-conditioned freezer dome to keep the bodies fresh. When Dexter brings in Lila West to see his dirty work, she becomes fascinated by seeing his dead body. Cepeda along with everyone else in the tent expires badly when Dexter later returns to sabotage the entire thing, turning each body into pink mush.
Detective Gonzales was assigned to him, with Cepeda's number being 9.
