The Gresham 4-year-old who shot himself in the finger on Saturday was using his grandfather's 9-millimeter handgun, Gresham police said Monday.

The boy, Deklinn Burian, and his family live in a Gresham apartment with his grandfather, 48-year-old Dana Burian.

The grandfather's gun was left on top of a gun safe in Dana Burian's bedroom when family members were gathered with friends in the 1100 block of Northwest 15th Street. Police said Decklinn walked into his grandfather's room, carried a plastic step stool over to the safe, picked up the gun, removed it from a holster and fired one round.

Police said family members thought Deklinn had entered the room to get a toy.

The bullet hit Decklinn's right index finger before ripping through a mattress and into the wall. The boy was taken to the hospital with non-life threatening injuries and released to his family Sunday morning. Doctors were unable to reattach a part of his finger.

Dana Burian is cooperating with the investigation and no charges have been filed.
