PITTSBURGH (AP) — A civilian who helped a New York police officer subdue a gunman who had already fatally shot another officer is one of 23 people being honored with Carnegie medals for heroism announced Thursday.

M. Neil Jones Sr., 60, was a valet supervisor who worked at Southern Tier Imaging, a radiology lab in Johnson City, when the shooting occurred March 31, 2014.

Two officers responded when a mentally disturbed employee created a scene. The worker grabbed the gun of Officer Dave Smith and fatally shot him in the head as Smith emerged from his patrol car, then engaged in a gunbattle with Smith's partner, Officer Louis Cioci.

Cioci wounded the suspect, then tried to subdue him. As that happened, the man grabbed for Cioci's gun and the officer called for help, with Jones pulling the suspect off Cioci until he could be handcuffed. Jones suffered a heart attack shortly afterward but recovered, and the shooting suspect died of his gunshot wounds.

Cioci was one of 13 U.S. police officers awarded the nation's Medal of Valor last month by President Barack Obama for risking their lives to save others.

The Carnegie Hero medals are named for Pittsburgh steel magnate and philanthropist Andrew Carnegie, who was inspired by stories of heroism during a coal mine disaster that killed 181 people, including a miner and an engineer who died trying to rescue others.

The Pittsburgh-based Carnegie Hero Fund Commission investigates stories of heroism and awards medals and cash several times a year. It has given away $38.2 million to 9,868 awardees or their families since 1904.
