Elizabeth L. Beth Nelson Cornelius was a 34-year-old Edmond woman, wife and mother of two boys, who was stabbed and killed on the evening of April 6, 2014 in northwest Oklahoma City. According to police, she and a friend, Allen Galbreath, were seated in a parked vehicle on Northwest 27th Street when a man later identified as Steven Rivera walked by, became involved in a brief verbal confrontation, and then produced a knife and attacked both occupants. Beth was able to drive a short distance to a convenience store at Northwest 23rd Street and Robinson Avenue, where she was transported to OU Medical Center and later pronounced dead. Galbreath survived and was treated at a hospital.

An off-duty Choctaw Nation officer who was visiting his mother in the area heard cries, confronted Rivera unarmed and ordered him to drop the knife; Rivera surrendered and was taken into custody. Detectives described the victims and suspect as having no prior relationship and characterized the assault as unprovoked beyond the brief exchange that preceded it. The family remembers Beth for her devotion to her husband, sons, and an active role in the BMX community. Does anyone have information about that evening or memories of Beth to share?
