James van der Beek guest stars in part one of two-episode story arc

A special two-part episode of CRIMINAL MINDS starts this week with Hotchner and the BAU team fearing they are facing a mission-based serial killer, or multiple killers, when a 911 phone call quoting bible passages from Revelations is placed by someone in a house just seconds before a wealthy couple is murdered.

As the team begins their profile, Garcia discovers that the killer sent out a video of the murders over the Internet just hours after they were committed.

Meanwhile, Hotchner, Morgan and Prentiss must determine how many people are actually responsible for the murders since different voices can be heard on the 911 recording and on the video.

CRIMINAL MINDS stars MANDY PATINKIN as Jason Gideon, THOMAS GIBSON as Aaron Hotchner, SHEMAR MOORE as Derek Morgan, MATTHEW GRAY GUBLER as Dr Spencer Reid, A.J. COOK as Jennifer Jareau, KIRSTEN VANGSNESS as Penelope Garcia and PAGET BREWSTER as Emily Prentiss, with special guest star JAMES VAN DER BEEK as Tobias Hankel.
