Officers say 20-year-old Tenacious Harris died Sunday morning at a Cedar Rapids hospital.
Harris was found suffering from a gunshot wound last Tuesday night in a car near Franklin Middle School.
Investigators recovered shell casings in an alley near the shooting scene.
They do not believe the shooting was a random act. No arrests have been made.
Anyone with information about the case is asked to contact the Cedar Rapids police or Linn County Crime Stoppers.
