GREENSBURG, Pa. -- A dangerous move in a chess game leads to a bullet just missing a baby in Greensburg.

The gun fire broke out at about 4 a.m. Thursday when Zachary Locov and a few friends were playing a game of chess while drinking alcohol.

At one point police said Locov took out a gun and pointed it at this head. A friend tried to disarm Locov.

That's when the gun went off and fired through the friend's arm, and into the kitchen of this home. Locov's 9-month-old son was playing on the floor of the kitchen at the time.

The bullet missed the baby boy by inches, but Lucov's mother defends her son and told reporters it was, "A stupid mistake."

Locov is being charged with aggravated assault and endangering the welfare of another person.
