A Monroe County man whose 4-year old son fatally shot himself in the face last year will spend up to two years in jail.

President Judge Margherita P. Worthington on Monday sentenced Ryan P. Koch, 23, of Chestnuthill Township, to one to two years in the county jail, followed by three years on probation.

Koch was charged by state police at Fern Ridge with felony charges of involuntary manslaughter and endangering the welfare of children after Bentley T. Koch found a loaded gun in their Ash Lane home around 11 a.m. June 18, 2017, and shot himself.

Bentley Koch was found at a home on Ash Lane in Chestnuthill Township, where Ryan Koch lived with his mother. Koch had custody of the child at the time.

According to testimony from the preliminary hearing, Assistant District Attorney Michael Rakaczewski said that Koch taught his son about guns, and normally kept it secure, but he smoked marijuana the night before and loaded a live round before leaving it out.

Koch on Sept. 7 pleaded guilty to the manslaughter charge.
