SAN DIEGO — Authorities asked for the public’s help in the unsolved murder case of Gai Wal, a 24-year-old man who was killed in a 2020 shooting outside a barber shop in the Encanto neighborhood.

Investigators said in a release Tuesday that they need assistance in identifying and locating two vehicles and two persons of interest in the area at the time of the gunfire.

On Dec. 23, 2020, officers responded to a shooting at around 5:51 p.m. in the parking lot of the Bars Up Barber Shop at 6281 Imperial Avenue, according to the San Diego County Crime Stoppers. When authorities arrived at the location, they found Wal — who had been shot — lying on the ground. The victim was taken to a local hospital but did not survive his injuries.

A green truck, red sedan and two people were being sought after investigators reviewed security video from the scene of the crime. Authorities said the truck appears to be a green extended-cab GMC or Chevrolet with grey, five-spoke wheels and a missing passenger door handle that has a small dent.
