Christopher Conway, 22, of the 4000 block of North 5th Street, and a 15-year-old juvenile both have been charged with murder, robbery and related offenses.
Police say the pair killed 52-year-old Sebastian Nunez Monday night.
Nunez, who worked at Condor Car and Limousine Service for five years, was found shot to death in the driver's seat of his limousine in the 4900 block of Bingham Street in Feltonville.
He is the second Condor driver to be murdered within the last two years.
