Factual error: Grissom does a quick analysis on the rough diamonds (chemical or laser) and immediately identifies the region of origin for the diamonds. He and Catherine then postulate that the diamonds are conflict diamonds. There is no way to identify the country or region of origin through any type of analysis. The United Nations and the world's diamond industry are looking for a way. http://www.reliefweb.int/library/documents/conflictdiamonds.htm http://pubs.acs.org/hotartcl/cenear/010212/7907sci1.html http://www.whitefirejewelry.com/wfbb/viewtopic.php?p=88&sid=b0e62206a64d98c81e53b600e053582f.
Continuity mistake: When Sara and Warrick are looking at the dead girl in the prom dress, she is turned over by the coroners and her hands are almost touching straight above her head. But when the shot changes, her arms have moved quite far apart.
Continuity mistake: The DB in the desert is in funeral pose. Sarah notices something on his hands, which are layed one on the other in a close shot. Cut to a wide shot and the top hand is off the other. Cut again to a close shot and it is once again atop the other.
Continuity mistake: When Grissom is in the horse stall, one shot shows the door closed to Grissom's back. Cut to the next shot (a closer shot through the door) and it's open.
Revealing mistake: The dead kids head on the blanket in Death Valley keeps changing position between shots.
