A person of interest connected to an attack where six people were gunned and many others were injured during a shooting at an Independence Day parade in Highland Park, a wealthy suburb of Chicago, has been captured following an hours-long manhunt. 

Robert Crimo III, 22, was taken into police custody after a brief car chase, Highland Park Police Chief Lou Jogmen said. A North Chicago police officer spotted the vehicle authorities alerted earlier in the day they believed might be driven by Crimo while he was on the run, Jogmen said. 

The officer attempted to initiate a traffic stop, but Crimo fled before he was stopped in Lake Forest, Jogmen said. He was expected to be questioned about his alleged role in the mass shooting, the chief said. 

Crimo is possibly linked to Monday's shooting that killed at least six people and wounded about two dozen more from a rooftop perch before fleeing, officials said. Five of those killed were found at the scene and were adults, authorities said. Another was taken to a hospital where they died.
