Continuity mistake: When the girls are first seen standing on the side of the road, Morgan has red sandals on; when she has her foot up on the bumper of the car, she appears to be wearing black sneakers and then has the sandals again when the shot pulls back.
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). (00:15:20)
Continuity mistake: The dead blonde girl's head changes from looking over her right shoulder to looking straight to looking over her left shoulder in three consecutive shots before anyone touches her.
Continuity mistake: Finn places a male symbol sticker on a board. First of all, the symbol is wrongly placed; the arrow should be pointing to the 2 o'clock position but It is at 5 o'clock. Next shot the arrow points to 7 o'clock.
The Fallen - S14-E19
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. (00:17:00)
The Fallen - S14-E19
Continuity mistake: Sarah Sidle is talking to Deborah Hughes in the hospital at the end of the episode. Shots from behind Deborah has her ponytail down her back, shots of her front has her ponytail over her left shoulder. (00:39:00 - 00:41:00)
Revealing mistake: The mom on Doc's table quite breathes, and her bottom lip moves slightly during the autopsy.
Answer: He doesn't have the authority to arrest him - when anyone is arrested in the show, a police officer does it. Also he tells Ty that he is going to be submitting his case findings to Ty's insurance company, who would no doubt contact the IRS, who then would have him arrested for fraud etc.
