Omar Zaragoza was 17 when he was fatally shot outside the Lucky supermarket in the 100 block of East 18th Street in Antioch, California on October 9, 2018. The shooting happened just after 4 p.m.; despite attempts to save him, he died at the scene. A memorial with flowers, photos, candles and balloons spelling out POLO — his nickname — was placed outside the store.

Antioch Police launched an intensive investigation and initially had no leads or motive. On October 19, 2018, three teenagers, two aged 16 and one 17, were arrested after a joint operation by the Violent Crimes Unit and the Special Operations Unit and booked into John A. Davis Juvenile Hall. The case was presented to the District Attorney’s office while detectives continued to work on motive and events leading up to the shooting. Some in the community questioned whether enhanced security at the store might have made a difference.

Anyone with information about Omar, the shooting, or security at the Lucky supermarket is asked to come forward.
