FULLERTON, Calif. (KABC) -- The suspect who killed two people and injured a third person during a shooting spree at five different locations in Los Angeles Tuesday has been identified as a 50-year-old man, but a motive remains unknown. Carlos Lopez-Melendez was killed during a standoff with police after a lengthy chase that ended on the 91 Freeway in Fullerton. Officers in police vehicles blocked in the white Jeep Cherokee around 4 a.m. near Raymond Avenue, and the suspect was shot by police at least once after allegedly opening fire on officers. The shootings - which occurred in the span of about 30 minutes just miles apart - appeared to be random in nature, according to Lt. Raul Jovel of the Los Angeles Police Department. Lopez-Melendez shot three men, two fatally, early Tuesday morning, Jovel said.
