ANTIOCH, Tenn. (WKRN) — A 16-year-old girl is dead and another student is injured after a teen shooter opened fire in a Tennessee high school's cafeteria Wednesday morning before turning the gun on himself, police said. Metro Nashville Police were called to the school shortly after 11 a.m. CT at Antioch High School, which has about 2,000 students and is located in a neighborhood of Nashville about 10 miles southeast of downtown. Police Chief John Drake said the 17-year-old boy — who, according to an Antioch High School student, participated in the school's Junior Reserve Officers' Training Corps (ROTC) program — “confronted” a 16-year-old female student in the cafeteria and opened fire, killing her.  That student has been identified as Josselin Corea Escalante by Metro Nashville Police. She was pronounced dead at an area hospital. Drake said police are looking into a motive and whether the students who were shot were targeted. The shooter then "shot himself in the head," police said. The teen, who died at the scene, has been identified as Solomon Henderson. What we know so far about the Antioch school shooter A male student, who has not been identified, suffered a graze wound. He has been treated and released from the hospital, according to Drake. Another male student was taken to an area hospital for a facial injury that happened during a fall.

The shooting had stopped before the officers reached the cafeteria, Metro Nashville Police spokesperson Don Aaron said during a news conference. Investigators with the Bureau of Alcohol, Tobacco, Firearms, and Explosives were also reportedly on scene. FBI spokesperson Elizabeth Clement-Webb said in an email that Nashville police had not asked for the federal agency's help in the shooting investigation as of early Wednesday afternoon. "The President and his team are monitoring the news out of Nashville," the White House said in a statement. "As details unfold, the White House offers its heartfelt thoughts and prayers to those impacted by this senseless tragedy and thank the brave first responders responding to the incident." Students describe harrowing moments inside Antioch High School Brandi Lemons, a student at the school, told Nexstar's WKRN she and her friends "took off running" after hearing gunshots, adding that she helped other students hide from the suspected shooter. Lemons said she also witnessed the suspected gunman turn the gun on himself. "I'm in shock," Lemons said. "It was right in front of me." Parents rush to reunification center after shooting at Antioch High School Shortly after the shooting, Sean Braisted, chief of communications and technology for Metro Nashville Public Schools, said in a statement that Antioch High School was on lockdown "due to shots being fired inside the school building." Braisted added that the school was "an active crime scene and investigation." Two students waiting to be reunified with their parents told WKRN they were locked in their classrooms. One said she had to sit in a closet until the lockdown lifted. Tactical officers were called in to clear the building and stabilize the campus as students were bused to a reunification center. What investigators have found so far Drake said the shooter is believed to have arrived at the school on a bus and retrieved the handgun from a bathroom. There may have been at least one "prior incident" involving the 17-year-old boy at the school, Drake said, though he said he was unsure of the details. A student told WKRN the teenager was a "smart person, top of the class, and was quiet and to himself." She said he also participated in the ROTC program at Antioch High School. Officials have not yet confirmed this information. Adrienne Battle, superintendent of Nashville schools, said public schools have implemented a “range of safety measures," including partnerships with police for school resource officers, security cameras with weapon-detection software, shatter-resistant film for glass, and security vestibules that are a barrier between outside visitors and the main entrance. “Unfortunately, these measures were not enough to stop this tragedy,” Battle said. Investigators have reportedly spoken with a parent of the shooter. Reunification process takes hours As the reunification process began, crews with WKRN found cars seemingly abandoned by family members rushing to the meeting site. Dajuan Bernard, waiting to reunite with his son, told The Associated Press that he first heard of the shooting from his son who “was a little startled.” The 10th grader was upstairs from where it took place but said he heard the gunfire. “His mom wants to homeschool anyway, so I don’t know. We might consider it,” he said. “This world is so crazy, it could happen anywhere. We’ve just got to protect the kids, and raise the kids right to prevent them from even doing this. That’s the hardest part.” Fonda Abner, whose granddaughter is a student at the school, said Antioch High does not have metal detectors that would alert officials to the presence of a gun. She said her granddaughter had called her a couple of times but that she only heard commotion and thought it was a pocket dial. They spoke briefly before being cut off. School shootings top of mind in Nashville In March 2023, a shooter killed three 9-year-olds and three adults at a private Christian elementary school in the city, The Covenant School. The tragedy prompted a monthslong effort among hundreds of community organizers, families, protesters and many more pleading with lawmakers to consider passing gun control measures in response to the shooting. However, in a Republican-dominant state, GOP lawmakers refused to do so. With the Republican supermajority intact after November’s election, it’s unlikely attitudes have changed enough to consider any meaningful bills that would address gun control. Instead, lawmakers have been more open to adding more security to schools — including passing a bill last year that would allow some teachers and staff to carry concealed handguns on public school grounds, and bar parents and other teachers from knowing who was armed. Antioch has endured other prominent shootings in recent years. A 2017 fatal shooting at Burnette Chapel Church of Christ killed one woman and wounded seven people. And in 2018, a shooter killed four people at a Waffle House. The Associated Press contributed to this report.
