I say we cap 'em both.
|― Emilio to Domingo about Walt and Jesse.|
Suspicious that Jesse ratted him out to the police (although it is later revealed Emilio was in fact a DEA informant), Emilio and Domingo force Jesse to lead them to his new partner. Emilio recognizes Walter from the time of his arrest and suggests killing both Walter and Jesse. Walter convinces them to spare their lives if he teaches them his meth formula. While the three are in the RV, Walt deliberately causes a chemical explosion and flees, trapping Emilio and Domingo inside the RV with deadly phosphine gas. Emilio dies and Jesse subsequently disposes of his body by dissolving it in hydrofluoric acid, albeit disastrously as it also dissolves Jesse's bathtub and the floor below.
According to Jesse, they met when they were still in elementary school.
Jesse mentions that Saul Goodman provided Emilio legal representation on at least two occasions, getting him acquitted both times despite much evidence against him (""). According to a mugshot which Hank has in an evidence file, one of his arrests occurred on November 8, 2002.("")
Emilio is arrested during a raid on a house in which the DEA is looking for meth supplier who goes by the street name "Captain Cook". Emilio makes bail and mistakenly suspects that his partner, Jesse Pinkman, ratted him out to the police. He forces Jesse to lead him and Domingo to his new partner, Walter White, in Emilio's 1980 Buick Regal. Emilio recognizes Walt from the time of his arrest and suggests killing both Walt and Jesse. Walt convinces them to spare their lives if he teaches them his meth formula.
While the three are in the the RV in the desert, Walt deliberately causes a chemical explosion and flees, trapping Emilio and Krazy 8 inside the RV with deadly phosphine gas and leading to Emilio's death. ("")
Emilio's corpse is subsequently disposed of by being dissolved in hydrofluoric acid in Jesse's bathtub. However, the corrosive acid eats through the bathtub and the floor, splattering Emilio's bloody, liquefied remains on the floor. ("") Walt and Jesse later clean up the mess which is then flushed down the toilet. ("")
While talking with gathered DEA agents about the new meth in Albuquerque and the disappearance of Domingo, Hank Schrader reveals that Domingo had been the one to rat out Emilio. Another DEA agent asks if Emilio could've been the one to presumably kill Domingo, but Hank admits that while that is a possibility, Emilio is also missing. Later, Skinny Pete and Combo ask Jesse about losing his partner Emilio who they have heard is either in jail or was bailed out by his cousin and skipped town. Uncomfortable, Jesse quickly brushes off the questions about Emilio. ("")
When Walt asks about selling their meth to a distributor, Jesse tells him that Domingo was his distributor and Emilio had been his in since Jesse knew Emilio since about third grade. However, they can't use Emilio as an in with Tuco Salamanca as he is also dead. ("")
When Walt discovers that Jesse is selling his house, Jesse comments as a reason that he's got "two dudes that turned into raspberry slushy and flushed down my toilet," referencing Emilio and Domingo. ("")
