Execution of Catherine Willows, Season 3 #6

The episode begins with man strapped to a table about to be executed. He gets a stay due to new evidence. He’s on death row having been convicted of murder 15 years before, a case where Catherine was a rookie CSI. And while Catherine is reviewing the evidence, another murder is committed with many of the same elements - the victim? A missing teenager (whose bedroom door has 3 locks on it) that Grissom, Nick & Sara had been investigating.

GREG:

1. Confronts Catherine about DNA evidence from old case going to another lab – he calls it cheating on him with an out-of-state analyst. She has to tell him he just doesn’t have the equipment.
2. Intercepted Catherine’s DNA analysis from federal lab, which doesn’t make her happy. And then he discovers that hair from current murder matches one of the victims from 15 years before.

Dark dress shirt, blue or black with tan/white stripes. Green t-shirt with lightening bolt.

REST OF TEAM:

• How come sometimes their cases are shiny and sometimes they’re not? Type of crime scene?
• Backyard of missing girls house - time for the big scanner again, last seen in Alter Boys. (Season 2 #6)
• Fancy footage of Mitochondrial DNA lab at Dept of Criminal Justice. It’s a clean room – which Greg’s lab isn’t. But does the federal guy have such cool hair? Doubt it.
• Warrick stumbles on railing with still-wet blue paint (which is kept in its wet form by addition of motor oil to paint). They had blue paint in earlier 3 murders but didn’t know about it. Now that they do, how does copycat know if their prime suspect is on death row?
• Catherine goes to prison to sit with the parents for execution. And blue-paint killer is still out there.

Grissom’s Lesson of the Week: Cicadas are one of the longest living insects. They spend 17 years underground and then emerges and shed their skin. They then fly around for 5 weeks after that as adult and then dies.
