Effective Range, Part One

A new murder victim forces the team to consider whether a notorious serial killer has resurfaced after 20 years, or if they are dealing with a copycat. Nikki and Jack investigate a murder bearing all the hallmarks of a notorious serial killer. When Nikki meets Charles Beck, the pathologist who conducted the original post-mortems, she discovers his wife was the suspected fifth victim of the serial killer, but nobody believes him when he claims he knows where to find her body.
