STONINGTON – A young girl and her father were wounded Sunday morning after the handgun he was cleaning went off by accident, Maine State Police said.

Stephen McCausland, spokesman for the state police, said 38-year-old Ryan Matson of Greenhead Road in Stonington was cleaning his .45 caliber handgun when it discharged around 9 a.m.

McCausland said the bullet wounded Matson in the leg and his four-year-old daughter, Riley Matson, in the thigh. The girl had been sitting next to her father when the gun discharged.

Both father and daughter were transported to a hospital in Blue Hill where they were being treated Sunday for non life-threatening injuries, McCausland said.

Charges will not be filed against Matson.
