Our Lady of Cement

The first case Guy ever worked on gets reopened when the victim's body is found. The daughter of the man convicted of the crime asks Guy to help her clear her father's name, but Guy is frustrated when the evidence continues to point in the same direction.

Full Recap
Twenty years ago, Guy's first case as a criminalist was the murder of Olivia Bellini. Guy's investigation helped convict Russ Bonner, a handyman, of the crime even though Olivia's body was never found. All that changes when her body is found during renovations on the building where she lived. Bonner's daughter asks Guy to re-examine the evidence to clear him of the crime; Bonner himself wants Guy to stay out of it so as not to jeopardize his upcoming parole hearing. Guy is frustrated when his investigation still points to Bonner as the killer. But when he discovers that Olivia may have been having an affair, and that more than one suspect has ties to police forensics, the case takes a new turn, and a 20 year old piece of evidence may be enough to set one man free and convict another...
