Henry Ernesto Martinez was 29 when he was shot and killed outside his apartment in Jacksonville, Florida, shortly after midnight on June 29, 2017. Known as Ya Boy H in the music scene, Martinez had recently moved to Jacksonville with his girlfriend and their one-year-old son. He released an album titled Bands Goin' Up in 2016 and had several music videos.

Neighbors at the Windy Pines apartment complex on 103rd Street reported hearing what they first thought were early Fourth of July fireworks; witnesses said a gunman ambushed Martinez as he returned with fast food, firing about 20 shots and continuing to shoot him after he fell, then rummaging through his pockets before fleeing. Police and paramedics responded quickly but Martinez died at the scene. No arrests were announced immediately and the motive was not clear; some speculated about a possible drug connection.

Did anyone in the Jacksonville area know Martinez, his movements that night, or have information about who carried out this ambush?
