The incident took place just after noon on Sunday, in the inner loop of Interstate 695 near the Harford Road exit. Police say the drivers of two separate vehicles — a white van and a dark-colored Nissan — were arguing, when a third vehicle, a 2018 Subaru Outback, attempted to pass them. Police said that either a passenger or driver of the Nissan then fired a single shot in the direction of the Subaru, which hit the car’s driver, a 58-year-old woman. The Outback then pulled over, and a passenger in her car called 911 and provided details to police.
