When Hannah takes a picture of herself to send to Tanner, she is wearing sunglasses. But when Tanner receives and sees the photo, she is not wearing sunglasses.
Grammatical errors: An article shown has the sentence "A lawyer of the suspect said his client, has nothing to do with the murder, and she was just happened to be in the wrong place at the wrong time." The first comma (between "client" and "has") should not be there and "she was just happened" should not have the "was."
Later on in the movie, after they have known each other for a while, Hannah calls Mr. Williams "Mr. Garrett," which is his first name.
