Don't just watch CSI. Live CSI (kinda).

This week, fans of the wildly popular CBS franchise, CSI, got the opportunity to don their detective gear and wrangle up "perps" in Second Life. Fans of the wildly popular web world, Second Life, I would imagine, are probably getting antsy. Who's killing all the avatars?

CSI: New York this week kicked off a story line where the shows' detectives began a man hunt (can you really call it that? Avatar hunt?) to catch a killer using the virtual world. Fans of the show are encouraged to sign up for a Second Life "life" and help bring the criminal to justice. According to reports, this will be an ongoing storyline that culminates sometime next February with the killer being apprehended.

Second Life is certainly gaining in popularity, but it won't fully be considered mainstream until Chris Hansen hosts an episode of "To Catch an Avatar."
