Efren Mendoza Jr. was 18 and from Long Beach, California, when he was killed in a shooting on January 5, 2009. The attack also wounded two other people. Police suspected gang involvement and asked the public for help identifying the shooters.

Investigators later added a reward for information that could lead to arrests, but the case remained unsolved for several years.

If anyone has information about that January 2009 shooting or remembers anything unusual from the area that night, please come forward to assist the ongoing investigation.
