If Westerfield was so anal that he called his son to check whether the front door was locked on his home then how could he ever have left the RV unlocked ?

Its called reaching the age of 50 and above. You tend to forget sometimes.

If Westerfield was so anal that he called his son to check whether the front door was locked on his home then how could he ever have left the RV unlocked ?

If you read his statement to police he indicates that he sometimes forgets and leaves certain doors to his house unlocked, from time to time, accidently.

If he was anal, he wouldn't have left it unlocked, necessarily. The supposition that he called his son to have him check means he thought he might have GOOFED AGAIN and left it open.
