Christina Echeverria, 24, was fatally shot on October 30, 2016, in Mendota, California. She and 24-year-old Angel Sanchez were walking home from a convenience store when both were shot; their bodies were found along the railroad tracks in the center of town about 5 a.m., though gunshots had been reported to police roughly three hours earlier. The Fresno County Sheriff’s Department took over the investigation from the Mendota Police Department.

Neither victim had known ties to criminal street gangs; both were described as single parents. Christina left behind five children, who are now living with their grandfather. No arrests or suspects have been identified, the motive remains unclear, and the case is open.

Anyone who knew Christina or Angel, or who saw suspicious people or vehicles in Mendota that night, is asked to contact investigators with any information that might help solve these killings.
