Alberto Rios, 20, of Villa Park, Illinois, was killed on May 6, 2017, in Addison at Elizabeth Drive and Denise Court. Police responded to shots fired and found a vehicle crashed into a tree with Rios and 17-year-old Kevin Bustos of Addison inside. Both were taken to hospitals and pronounced dead of gunshot wounds.

Investigators say an earlier altercation had occurred between Rios and 20-year-old Jorge Vargas of Addison. After an initial argument, Rios reportedly fired shots into the air, left the scene, and left threatening messages on a mutual friend’s phone about returning to cause harm. About 20 to 30 minutes later Rios returned as a passenger in a car driven by Bustos. Vargas was waiting at a third-floor window and opened fire on the vehicle, killing both occupants.

Does anyone have information about the night of May 6, 2017, or knew Alberto’s movements that evening?
