GREENVILLE, Miss. (AP) — Police in Mississippi say a 9-year-old boy has died after being shot with a pellet gun in his home, and an initial investigation shows his 8-year-old brother accidentally did the shooting.

The shooting happened Wednesday evening in Greenville.

The city’s assistant police chief, Michael Merchant, says an investigation suggests the younger child accidentally shot his brother. The 9-year-old boy was taken to Delta Regional Medical Center, where he died.

Merchant tells The Associated Press that parents were in the home when the shooting happened. Officers found the air pellet gun inside the house.

No charges had been filed as of Thursday morning. Merchant would not release other details about the investigation, or the name of the child who was killed.
