Prosecutors have told an Oneida County jury a 29-year-old woman abused her stepson until he died. Ellen Tran is facing a charge of reckless homicide. Twenty-month-old Avery Edwards died of head injuries last year. The defense says Tran’s ex-husband, Trung Tran, is responsible for the child’s death. His testimony was cut short Monday after he pleaded the Fifth on several questions from the prosecution.
