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.
