On the night of March 9, 1992, 52-year-old Martha Doney is discovered in her Las Vegas home, assaulted and brutally stabbed. Homicide detectives work around the clock to find justice for the single mother of three. Could the killer be someone close- the ex-husband who shared a tumultuous relationship with the victim, or the hot-tempered boyfriend who left town within hours of the crime? Was Martha the victim of a robbery gone wrong, or was an act of kindness used as a ruse for murder? Investigators believe they know the answer, but without solid evidence, no arrest is made. Years later, modern technology breathes new life into the investigation, bringing the case to a surprising conclusion.
