A Mason City man who was accidentally shot in a leg by his 4-year-old son has been fined $625.

29-year-old Christopher Upenieks had pleaded guilty to misdemeanor child endangerment after prosecutors agreed to drop a charge of allowing a minor access to a loaded firearm.

Upenieks was shot in his left knee Feb. 27 when his son found an unsecured handgun in his dad’s truck and the gun fired.

Upenieks was in his truck when police arrived. Police say he had a valid permit to carry a gun.
