National City police have identified the 12-year-old boy killed in a shooting at a party in an abandoned house late Friday night. Police said Sunday that Elijah Smith was killed in the shooting, which occurred at a property on N Avenue near 8th Street, that left four others injured. Multiple 911 calls came in about 11:50 p.m. Friday reporting shots fired at the property. National City police arrived to find more than 100 people at the party — mostly teens and young adults — and asked for assistance from neighboring police agencies for crowd control and to secure the scene. The shooter or shooters fled by the time law enforcement arrived. As of Sunday, there was no one in custody for the incident, police said. Police reiterated Sunday that it appears that the shooting proceeded some type of physical altercation between two groups, and that they were still looking for and trying to identify witnesses. The other four victims, all males, all had suffered gunshot wounds. They were reported in stable condition, police said Sunday. Anyone with information about the shooting was asked to call police at 619-336-4411 or leave an anonymous tip with Crime Stoppers at 888-580-8477 or sdcrimestoppers.org.
