Police said the victims were in a blue Honda hatchback in the 2600-block of North St. Louis Avenue at about 1:05 a.m. when two suspects got out of a dark-colored Hyundai and approached.
One of the suspects took out a handgun and ordered the 22-year-old man driving and his 20-year-old female passenger to exit the vehicle, which they did, police said.
