Continuity mistake: Isaac told Christine he would give Elijah his phone back and grabbed it from her. Isaac had the phone in his right hand when he turned to go out the door. When Isaac came out the front door, he was not holding the phone in his hand and it did not look like the phone was in any of his pockets. Isaac had police equipment around his belt (not the phone).

Deliberate mistake: The number of clicks (sounds) Christine made on the "text to talk" device did not match the total characters she typed. With few exceptions, there were a lot less clicks/sounds than there should have been based on the amount of letters/words she typed. (00:06:40 - 00:15:30)
Revealing mistake: Christine closed her dead brother's eyes without actually touching them. Christine had an open hand (no cupped palm) with her fingers straight out and together; her pinkie finger touched her brother's nose, meaning her other fingers would have been too far away from his eyes and unable to make contact.
