OK, the following is a DEADSET SPOILER from the Stargate Atlantis episode Vegas, prod # 519.
When another body turns up in the desert outside of Las Vegas, Nevada, Detective John Sheppard (Joe Flanigan) is called in to investigate. Sheppard is a homicide detective, but the murderer he has to hunt down now is unlike anyone -- or any thing -- he has ever seen.
"Sheppard tries to dodge a news reporter when he arrives at the crime scene. The reporter suggests that, if this victim is like the others, the city may have a serial killer on its hands." To read the rst if you're game, go to Stargate Atlantis Season 5 Episodes Shed over at The Happy Place Forums.
