An 11-year-old boy was killed by his 8-year-old brother in an accidental shooting Saturday in Harford County, Md., the county Sheriff’s Office said.

The 11-year-old, who lived in Pylesville, was shot in the head in local woods, the authorities said.

Deputies were sent to the scene, about 70 miles northeast of Washington, shortly after 7 a.m. in response to the report of a shooting, authorities said. Rescue personnel were on the scene, but the boy died soon after.

Deputies were told at first that an unknown person had fired from an unknown direction, but they found a handgun hidden in the woods, the Sheriff’s Office said.

Authorities said the older boy was shot accidentally by his brother as they were playing.

The gun had been taken from a secured area on the property of an elderly neighbor when the boys went to his house to help with yardwork, authorities said.

No charges had been filed, and the county prosecutor’s office would review the incident, authorities said.
