PHOENIX -- Authorities say one suspect is in custody after a security guard was found fatally shot in a car in south Phoenix.
Phoenix police identified the victim as 54-year-old Christopher L. Cipolla.
They say 19-year-old Aric Eugene Robinson has been booked into jail on suspicion of first-degree murder and a second suspect in the case is being questioned.
Police say the car crashed into a shopping center's parking lot wall before dawn Monday in the area of 35th and Southern avenues.
