The teen was riding in a car in the 1600 block of North Los Robles Avenue, three blocks north of Washington Boulevard, at 3:03 p.m. when police received a call from the Pasadena Fire Department regarding a gunshot victim, said Lt. Marcia Taglioretti of the Pasadena Police Department.

The condition of the second victim was not immediately known.
Detectives were working to determine if the two shootings were related.
No suspect description was provided.
