Can You Help the NCIS Team Untangle a Gruesome Web?

This Tuesday at 8 pm/ET — in a special Halloween-themed outing titled "Murder 2.0" — the NCIS team will be put on the trail of a seriously sick serial killer who plants inside (!) each victim a link to a website which offers clues about his next attack.

Although it ultimately will be up to Gibbs & Co. to visit and analyze each URL (which serve up video spliced with fleeting images/clues pointing at the place, time and method of murder), the NCIS faithful are being given an opportunity to deduce the who, when, how and where of the perp's very first kill by logging onto his/her very first URL, Primitus-Victor.com.

While there is nothing you can do to save this first victim, there's something to be said for cracking the first code. Viewers will find out if they guessed right when the hit CBS series' Oct. 28 episode opens.
