The synopsis at http://www.uni-television.com (which was presumably taken from an earlier draft of the script) has Juan in the car with Kiki at the time of the accident. Juan then flees the scene and returns to the Chinese family's home before being killed. Which, unless he's the world's dumbest criminal, doesn't really make much sense.
Not the same character Emilio Rivera played in "A Life of Its Own." There, he was on the other side of the law.
