Police arrested four suspects Wednesday in the fatal shooting of a man and a teenage girl the night before on the Chino Valley Freeway in Pomona.

Police found a car late Tuesday off a freeway embankment with the bodies of Monique Almanza, 15, of Ontario and Raymond Flores, 22, of Covina.

They later arrested three juveniles who reportedly had argued with the victims at Walnut Park in Chino. Also arrested was Carlos Paredes, 26, of Fontana.
