NEW YORK (AP) — A construction worker who alerted police to a gunman who shot a former coworker near the Empire State Building says he was determined to stop the shooter from getting away.

Brian Dillon tells the Daily News ( ) that he saw Jeffrey Johnson walking away into the Fifth Avenue crowd after Friday's shooting.

Police say Johnson killed Steven Ercolino outside a building where they had worked together.

Dillon was working on a loading dock outside the Empire State Building when he saw Johnson pumping shots into the head of a man on the sidewalk.

Dillon followed the gunman and flagged down two officers. Johnson pulled out a gun and was shot to death. Nine bystanders were wounded.

Dillon says he's just glad he was there to help.
