The First 48

What Lies Beneath/Back for Blood (10x8)

:

When a man arrested for a domestic dispute claims his boyfriend killed someone seven months earlier and buried the body in the basement, Louisville Detectives Jon Lesher and Collin King are launched into one of the strangest cases of their career. Detectives are initially skeptical of the man's claim, but after hours of digging in a hot, humid basement, they discover the truth: buried five feet below the dirt floor is a large plastic storage box containing human remains. Detectives must now determine if the man accused of the murder is a cold-blooded killer, or if a vindictive lover is out to frame him. And in Charlotte, a 55-year-old father of three is stabbed to death and left for dead in the middle of a residential street. Det. Susan Sarvis and the homicide team initiate a citywide hunt for the last man seen with the victim to find out if he is a witness or if he's responsible for the homicide.
