Unusual Suspects

There's a reason murder investigations don't begin with preconceived notions. Sometimes those least expected to be capable of committing such dark deeds -- respected role models and trusted members of the community -- can have a sinister side. "Unusual Suspects" documents baffling, challenging investigations, actual cases that were anything but cut and dry. Episodes feature in-depth interviews with leading law enforcement personnel combined with stylized re-enactments, illustrating how illusive offenders evaded capture for years before being undone by persistent police work.
