CSI: Crime Scene Investigation, Season 7

Keppler:
In theory, as the killer gets more and more comfortable after each act, the locations of the bodies should spiral outward from one central point.

Warrick:
I'll tell 'ya one thing your dump sites do have in common.

Keppler:
What's that?

Warrick:
When the bodies were found in the location they were at the time had the highest crime rate in the city.

Keppler:
Smart. Your crime center sure seems to move around here a lot, huh?

Warrick:
Well, in Vegas new is old in 5 years. Old is history in 10, and nothin' ever seems to leave a mark.

Keppler:
Sounds refreshing.
