Continuity mistake: The son of a CSI is waiting in a hospital hallway. He is sitting on a bench with his elbows on his legs and his hands fisted together on his chin, holding a red jacket. Morgan approaches him, and the next shot shows him with one his left hand across the right leg and the right under his chin. The jacket is also in a completely different position.
Factual error: DB Russell gives Mark Roberts a bottle of water to hold. In the blood he leaves his fingerprint on the bottle. Stokes is watching with another policeman the CCTV footage from the interview room. Stokes then says grab a screen shot of the water bottle. They zoom in and low and behold they get a totally clear fingerprint. No way to get that much clarity from a CCTV camera.
Character mistake: When Russell is reading the bio for the suspect who had dressed as a reindeer at the party and was looking for her contact lens, the bottom of the page lists "Identification Databases Checked:" and lists several states and 5 cities under each one.Alabama and Colorado have the same 5 (Alabama) cities listed. Also, the form lists several pieces of information - Class, DOB, Height, Weight, Eyes, Eyes, Hair, Restrictions, Contact Lens Serial No and Criminal History and Occupation. (Yes, "Eyes" is there twice.) The first "Eyes" field lists a name (emergency contact?), which illustrates how badly the prop department prepared this form. Lastly, despite the suspect's DOB being 04.12.1987 (either April 12 or December 4), and this episode taking place in December 2013, Russell states that she is 23 (but should be 26).
