Timothy Andrew Koppos was 12 when he was shot and killed in his Alhambra, California home on April 22, 2001. The Los Angeles County coroner’s records list the death as a gunshot fatality that happened at the residence where Timothy lived with his siblings and grandmother.

According to accounts of the incident, a violent confrontation that morning involved Timothy’s older sister, Colleen Koppos, and her boyfriend, Daniel Arzaga. Tensions escalated after Arzaga, who had recently been released from the California Youth Authority, accused Colleen of infidelity, brandished a gun and refused to let her leave. After a brief lull the situation deteriorated and Timothy was shot; the incident also involved attempted murders of Colleen and the children’s grandmother, Bertha Tate. Arzaga was arrested and charged in connection with the shooting.

The killing of a child in the family home shocked the community. If anyone knew Timothy, his family’s situation, or has information about what happened that morning, please come forward.
