The incident happened in the middle of the afternoon Sunday on St. Vincent Circle.
A man and woman say they were sitting in a car when a man jumped in the back seat and demanded cash. That gunman then shot the male driver.
After shots rang out, the gunman ran off and the driver left the car and took off after him.
The woman in the passenger seat drove the car and followed the shooting victim. He was eventually taken to a hospital where he was treated for his minor injuries.
The suspect remains on the run.
