ALISO VIEJO, Calif.—A man was fatally shot outside a condominium complex in Aliso Viejo that has had recent gang activity, authorities said Friday.

Deputies sent to Via Jacinto and Via San Miguel found the mortally wounded man, and paramedics pronounced him dead at the scene about 12:15 a.m., said Carrie Braun of the Orange County Sheriff’s Department.

Authorities withheld the name of the man, who was in his 20s, pending notification of his relatives.

There is a “strong possibility” the shooting was gang-related, Braun said.

Deputies were continuing to look for the gunman, Braun said.

Anyone with information on the case was urged to call 949-770-6011, or OC Crime Stoppers at 800-TIP-OCCS.
