Andrea Olague was 14 when she was fatally shot at a house party in the 700 block of East I Street in Ontario, California, on January 28, 2015. Police say the shooting occurred about 8:35 p.m.; a gun was produced during the gathering and Andrea was shot in the presence of several others. A handgun was recovered at the scene.

A 20-year-old man was arrested in connection with Andrea’s death; authorities described him as someone who knew Andrea. Officers were initially looking for two men and a woman seen leaving the house in a black vehicle shortly after the shooting, though it was not clear whether those people were involved or merely witnesses. Investigators collected evidence and interviewed witnesses while trying to determine whether the shooting was intentional or accidental.

Friends and family remembered Andrea as vibrant and joyful. Does anyone who attended that party or knew Andrea have information that could help clarify what happened that night?
