An 18-year-old man shot April 13 on a Carson street has died, family members said.

Justin Uy, a star Carson High School volleyball player, died at 8 p.m. Wednesday at County Harbor-UCLA Medical Center. He was on life support — with no brain activity — since the shooting.

Uy’s death came just one day after the Carson City Council approved a $20,000 reward for information leading to the arrest and conviction of the assailant.

The investigation, which was in the hands of the Carson sheriff’s stations gang unit, was taken over Thursday by department’s homicide investigators.

Uy was shot as he stood on the sidewalk at 228th and Dolores streets. Detectives have no suspect descriptions.

The Daily Breeze named Uy in March as one of the South Bay’s top 10 volleyball “players to watch.” Uy was set to graduate this year and attend college in the fall.

Anyone with information about the shooting was asked to call the homicide bureau at 323-890-5500.
