“ID introduces a new team of cold case investigators.”

Former Rhode Island police detective Derrick Levasseur and forensic psychologist Kris Mohandie answer the pleas of desperate families and investigate the cold case murders of their loved ones. Some of the cases they explore may be complete mysteries, others may have a strong "person of interest" but not enough evidence has been gathered to get a conviction. Derrick and Kris apply their unique talents and investigatory skills as they re-examine original clues and chase down new ones in an effort to solve these cases once and for all.
