At age 17, a guilt-ridden Lena Chapin confessed to helping her mother dispose of her murdered stepfather’s body four years prior. In 2012, Lena was issued a subpoena to testify against her mother in court, but the authorities were never able to deliver the summons — because Lena had disappeared, leaving behind a young son.
