Detective Steve Spingola joins veteran prosecutor Kelly Siegler in Rio Arriba County, N.M., to investigate a bizarre case involving a man who evidently died of natural causes, based on outward appearances. As this new episode "Unnatural Causes" reveals, however, when postmortem scans revealed a previously undetected gunshot wound, the man's death sparked a murder investigation. Now Siegler and Spingola hope they've picked up the trail again in time to find the killer.
