It's been discussed a few times, the person guessing at the make of car, is guessing about the same parked car that was backed in and parked, that others also guessed about, also incorrect. Why keep giving any importance to that wrong guess, instead of the other wrong guesses? LE already said they believe they saw the Ford Focus owned by RA on video.
There is no reason to doubt that RA drove and backed in and parked as described in the affidavit. Also never shown that TK or his "close" relative ever drove a purple car in Delphi or anywhere else, except by rumor started after it was seen in the affidavit, and someone took a picture of a car which was never verified belonging to a relative. Did you see the license plate or registration?
