CSI: Crime Scene Investigation

Richardson: (on the letter) To my colleagues, who have shared the burden of the badge. Many of you won't agree with my methods, but all of you will understand what it's like to have all the pieces set before you, the picture painted broad and clear, and watch the killer walk away to live the life they tore from others. Well, I could not let that continue. I made a list. Five names. Those most deserving of vengeance. And now, as I embark into life's last mystery, I do so in peace. Detective Stanley Richardson, Las Vegas Police Department.

Hodges: The trace you got from your motel vic's face is pollen. From the flame lily. The particles, not unlike one David Hodges, exhibit a highly-sculptured outer shell.
Morgan: Helps them cling to passing bodies in desperate hopes of propagation.
