City officials previously withheld identifying the 16-year-old, who was an employee at the Virginia Walmart, “due to him being a minor.”
Police identified Chavez-Barron following a vigil on Thursday honoring all the victims killed by 31-year-old Andre Bing, an overnight team leader at the Walmart who had been with the company since 2010.
Family, friends and classmates of Chavez-Barron gathered by a tree close to the store’s front entrance and recited the prayer Hail Mary on the rosary in his memory, NBC affiliate WAVY of Portsmouth reported.
Authorities say Bing killed at least six people and injured at least six more before taking his own life in the Tuesday night shooting.
There were believed to be about 50 people in the store when the shooting started, police said.
Shaundrayia Reese, 27, who worked on the overnight stock team with Bing from 2014 to 2018 described Bing as “just weird.”
“He put tape on his phone, on the camera. Always used to tell us the government was watching,” Reese, who lives in Chesapeake, said.
City officials on Wednesday identified five of the victims: Lorenzo Gamble, 43; Brian Pendleton, 38; Kellie Pyle, 52; Randall Blevins, 70; and Tyneka Johnson, 22.
