CSI: Crime Scene Investigation
The Execution of Catherine Willows

A triple murder case from Catherine's rookie year is the focus of this intriguing installment.
Fifteen years ago, Catherine (Marg Helgenberger) helped put John Mathers (Victor Bevine) on death row for the rape and murder of a coed at a nearby college. Her body was dumped in a trash bag, and two other girls found the same way were also linked to the suspect. As the episode opens, Mathers is about to be executed when he's granted a stay based on new DNA evidence. But while Catherine awaits the results of tests on hair samples found on the first victim, another girl at the same school is murdered...and discarded just like the first three---meaning the wrong man could be behind bars.
