Authorities say a third student's injury in a South Carolina school shooting did not need medical attention.

The Anderson County Sheriff's Office said Tuesday the child's minor injuries were discovered during the police investigation. Lt. Sheila Cole says the child was on the playground at Townville Elementary last Wednesday when a 14-year-old boy opened fire. But authorities have given no other details about the student or type of injury.

As a result of the third student's injuries, Solicitor Chrissy Adams added another attempted-murder charge against the 14-year-old. Her news release Monday evening marked the first time authorities had mentioned a third child victim.

The teen now faces two murder charges for last Wednesday's shooting: He is accused of fatally shooting his father at their home before driving to the school. Adams upgraded an attempted-murder charge after 6-year-old Jacob Hall died Saturday.

Jacob's funeral is Wednesday morning at Oakdale Baptist Church in Townville. The church is expecting an overflow crowd.

A first-grade teacher shot in the shoulder and another student shot in the foot were treated and released the day of the shooting. The teen faces two attempted-murder charges for those shootings.
