NASHVILLE, Tenn. (WKRN) – Three teens are facing charges after a shooting Thursday afternoon inside the restroom of the Nashville Public Library’s Bordeaux Branch on Clarksville Pike.

According to Metro police, two brothers, ages 15 and 16, reportedly followed a 14-year-old boy from a distance as he and another 15-year-old boy walked into the library. The brothers and the 14-year-old reportedly live in the same neighborhood and had been engaged in an ongoing dispute.

Shortly after entering the library, the brothers and the 14-year-old walked into the men’s restroom where police said multiple shots were fired. The 16-year-old allegedly shot himself in the foot and also shot the 14-year-old in the groin, according to investigators.

Police said all of the gunfire was confined to the restroom and no one other than the three teens were in the restroom at the time of the shooting.

The teen shot in the foot ran out of the library, but was later found on nearby Kingview Drive where he was treated for his injury and transported to Skyline Medical Center, while the teen shot in the groin stayed in the restroom where a library staff member helped him until paramedics arrived and took him to Monroe Carell Jr. Children’s Hospital at Vanderbilt, according to authorities.

Both teens are expected to fully recover.

Investigators said a semi-automatic pistol was found in the 14-year-old’s clothing. It appears he fired at least one shot in the library’s restroom.

An initial check of the gun revealed it was not stolen; federal authorities are now tracing the gun to determine the last registered owner, according to police.

Authorities said the brothers are being charged with attempted criminal homicide, reckless endangerment, and unlawful gun possession, while the 15-year-old who lead the 14-year-old to the library is being charged with conspiracy to commit criminal homicide as he was allegedly working with the brothers.

Potential charges against the 14-year-old will be discussed with the District Attorney’s Office.

No other information was released.
