Elianna Costello was 16 and from Santa Ana, California, when she was fatally shot on November 12, 2018. She was survived by a one-year-old daughter. Law enforcement investigated the shooting as a homicide and conducted interviews, forensic work, and community outreach, but no suspects were immediately identified following the shooting.

The case drew local and wider attention because of Elianna’s age and the presence of a young child in her family. Authorities asked the public for help as they continued to search for clues; details about arrests or named suspects were not released at the time. The investigation remained ongoing as officials worked toward locating those responsible.
