While Margot is driving in her a Camry, a sunroof is seen above her head. When the Camry is pulled out of the lake, there is no sunroof on that car.
(at around 56 mins) After the car is removed from the lake it is reported that the envelope of cash was found on the passenger seat. When Dad reviews the scene photos (at around 1h 3 mins), the envelope can clearly be seen inside the glove box.
(at around 1h 5 mins) The injury on David's jaw disappears while at his brother's home. Later, it reappears.
(at around 55 mins) Detective Vick declared "abduction" status at 8:54AM but the Amber Alert can be seen to be from 8:45AM.
(at around 1h 6 mins) While at his brother's house, David announces that he has to go to his car for a minute. In the hidden camera footage from the living room, both of David's hands are out of his pockets, but in the footage from the kitchen (which is supposed to be simultaneous), his right hand is somehow in his pocket.
(at around 33 mins) When David goes on Margot's Tumblr page, the URL reads www.tumblr.com/blog/mkmania01, but the URL format when viewing this blog would be mkmania01.tumblr.com. David also reaches Margot's tumblr page from clicking the "Log In" search result, suggesting she was already logged into the account on her computer. However, it would have taken him to her dashboard, not her blog. There also would not have been an option to "Follow" in the upper right corner.
(at around 34 mins) When David visits Margot's Bank of America page, it indicates on her account that she is a Preferred Rewards Gold member. However, Bank of America requires users to have an account balance of at least $20,000 before being eligible to enroll as a Preferred Rewards Gold member.
(at around 1h 21 mins) In the San José area, there is no such thing as SVPD (Silicon Valley Police Department). Each city has its own police department: SJPD (San José), MHPD (Morgan Hill), or GPD (Gilroy).
(at around 1h 1 min) Derek Ellis punched David in the left side of his face, but it appears that the injury is shown to be on the right side of his jaw because some of the footage of David from his webcam is flipped, as some webcams do.
(at around 33 mins) Detective Vick refers to "the 101" and "the 152" when referring to Northern California, specifically San José area highways. The use of "The" is common in southern California when mentioning freeways or highways. However, in Northern California it is not used. The scriptwriters, obviously from SoCal, missed that.
(at around 2 mins) Early in the film, the very young version of Margot is shown learning to play the piano on a Yamaha DX7. This is extraordinarily unlikely, as that is a digital FM synthesizer from 1984 which has neither built-in speakers nor a pleasant acoustic piano simulation, and its keyboard is unweighted, like a cheap home Casio.
Very shortly afterwards, she is seen playing a tune on, yes, a cheap home keyboard, with the soundtrack following her - badly. The notes she plays are completely different than the soundtrack.

(at around 25 mins) A law enforcement officer would not choose to show the face of their children on social media, for fear of repercussions.
