Kelly travels to Abbey Abbondandolo's home state to work with the Idaho Falls PD to help investigate the 2007 homicide of a young mother. When her body was discovered almost 3 years later outside the city, it left a family searching for her killer.

Kelly and Tonya work with the Fort Myers Police Department on the 2016 murder of Heyzel Obando, a young Fort Myers, Florida mother shot to death in her own home. It will take old-school interrogation techniques to catch her killer and bring justice to her grieving mother.
