A 9-year-old boy was in critical condition after being shot in the chest with a BB gun while playing a game called "one pump" with a 26-year-old man, Madison County sheriff's deputies said.

Edward S. Highers, 26, of Radnor Road, Morrisville, was charged with felony first-degree assault, felony first-degree reckless endangerment and misdemeanor endangering the welfare of a child, officials said.

Deputies first learned of the incident when they responded late Thursday night to Hamilton Hospital for a report of a child who had been shot in the chest with a BB gun. The investigation revealed that Highers shot the boy with a BB gun while playing a game in which people take turns pumping the BB gun and shooting at each other, officials said.

On one occasion, Highers pumped the gun several times and shot the boy in the chest, causing the BB to become lodged inside the boy’s skin next to his heart, deputies said.

The boy eventually was transported to a Syracuse hospital.

Highers was arraigned in Town of Hamilton Court and sent to Madison County jail on $10,000 bail or $20,000 bond. Highers is scheduled to return to court Monday to answer the charges.
