MNPS begins weapons‑detection pilot at Antioch High after cafeteria shooting; students press for broader change

At a Metro Nashville Public Schools board meeting, district leaders announced a pilot deployment of an Evolv weapons‑detection system at Antioch High School as part of the district’s immediate response to a cafeteria shooting earlier this month that killed a student.

The announcement came as board members and student representatives paid tribute to the student who died and pressed for both immediate and longer‑term changes to prevent future violence. Director of Schools Dr. Adrienne Battle described a combination of safety measures already in place and said the district moved quickly to add the Evolv system at Antioch this week.

The pilot is intended to be part of a layered approach to school safety, Battle told the board, combining physical measures — security vestibules, AV intercom locks, badge access, shatter‑resistant window film and existing surveillance systems — with personnel and student supports. “We’ve worked hard over the past six days to understand the tragedy at Antioch High School and make adjustments to make our students and staff more safe and ensure they feel supported,” Dr. Adrienne Battle said.

Evolv Technologies’ vice president for education, Jill Lamond, described the system to the board and said Evolv’s detectors are in use at large public venues and in more than 1,200 U.S. school buildings. Lamond said the system scans people and belongings as they walk through dual lanes and produces an image with a red box to indicate the location of a potential threat so staff can perform a targeted secondary check. “The whole goal is for students to be able to keep as much as they can,” Lamond said, adding that in practice students remove laptops for screening and, when a secondary check is required, staff perform a quick, focused search.

Students and student board members told the board they want concrete action on safety and mental‑health supports. Student board member Christina Tran said many students are frightened and called for change: “How many kids have to be scared and cautious before something is done? How many kids have to succumb to gun violence before something is done?” Hannah Wynne, another student board member, urged continued advocacy at the state level for mental‑health resources and stronger laws.

Board members questioned operational details. Member Mays asked about throughput, where students wait, and how often the district will report pilot findings; staff said the system moved students through efficiently on the first day and that the district intends to collect feedback during the pilot. Director Battle said the pilot was “for 30 days at this time” and that the district would provide the board with an evaluation and information needed to consider expansion.

Board members and staff emphasized relationships and prevention alongside technology. Member Tyler and others said that hardened security must be paired with trusting adult‑student relationships that encourage peers to “say something” when they see concerning behavior. Battle reiterated that the district is maintaining and expanding counseling, restorative practices and threat assessment protocols.

Several public commenters urged broader, districtwide deployment of metal detectors. Leland Evans said he represented more than 2,500 petition signers demanding metal detectors at all schools and criticized reliance on cameras and other systems. Other speakers praised district staff and community organizations that offered immediate support to students and families in the aftermath.

Formal board business at the meeting included two procedural votes. Board member Mays moved to adopt the agenda, seconded by Aaron O’Hara‑Block; the motion passed. Later the board approved the consent agenda on a unanimous voice vote after a motion by School Member Young and a second by Vice Chair Nabon and Kenny.

The district also described other security tools in use or under consideration: the OmniAlert AI weapon‑detection software tied to security cameras (which did not trigger during the Antioch incident because of the shooter’s position and the near‑immediate police response), expanded school‑resource officers and additional community police visibility. Battle said the district would continue to work with the Metro Nashville Police Department on threat investigations and that some students have been arrested in connection with related online threats.

The board and district leaders acknowledged limits to local authority and funding. Battle said large‑scale procurement of weapons‑detection systems is a significant investment and that broad expansion would likely require both local and state funding or grants. She said MNPS is exploring how to pilot additional sites, starting with other high schools, but that any districtwide plan would return to the board with cost and operational details.

The meeting closed with expressions of gratitude to first responders, school staff and community partners and with promises of continued outreach to students and families as the district moves through the pilot and recovery period.
