A title card prior to a visit to the home of the victims was grammatically incorrect. The last name of the victims is "Winters" but the title card reads "Winter's Apartment" when it should be "Winters Apartment" or "Winters' Apartment".
In the first scene, at the time of the murder, baby Andrew is stated to be 19 months old, in years, that means he is one year and 7 months old. Later on in the court trial ADA Stone states that he would of celebrated his first birthday not too long ago (in the interim between crime and trial). In actuality, baby Andrew would of turned two.
