A 3-year-old boy shot his 18-month-old brother in the head in Tennessee.
The Coffee County Sheriff's Department said the little boy shot his sibling with a .25-caliber automatic pistol in a home Tuesday afternoon in the community of Hillsboro, which is about 70 miles southeast of Nashville.
The 18-month-old was transported to a local hospital.
Sgt. Danny Ferrell told The Associated Press that investigators are still trying to determine how the 3-year-old got access to the weapon.
His condition was unknown late Tuesday.
