Duvall, 18, was a passenger in a car that hit a tree on Friday night and died at the scene, while a 16-year-old driver and another teen suffered life-threatening injuries.
Police said speed has not been ruled out as a contributing factor, and one additional passenger had non-life-threatening injuries as investigators continued examining the crash.
Peers at Quest Martial Arts Center remembered Duvall as humble and hardworking, while Baltimore County Public Schools confirmed one teen involved was a Dulaney High School student.
