Max puts CSI on lockdown when proof in another homicide tips Grissom and Sara to another suspect in the investigative laboratory. Additionally, Folsom and Allie research a progression of chilling killings at a weather-beaten jokester-themed inn.
Grissom and Sidle followed the luminol they recently found at an instance of a man who detonated from a projectile. Appears to be the executioner who utilized it to find and clean their own blood as they got harmed in the impact.
Not really set in stone the synthetic came from their lab-something that Grissom made back when he ran the lab. Roby fought everybody to announce it a crime location and quest for who perhaps released the luminol.
