Popolozio?s car ended up flipping during the high-speed chase. He was taken to University Hospital with severe head injuries and died a short time later, police say.

Authorities say the suspect was found near the scene of the chase later. Mayor Cory Booker called Popolizio's death "the greatest tragedy of my administration."
