"yeah. they usually bump 'em off. they're scared of 'em after they get 'em. they think they might identify them afterwards."(p.192)
What bigger did was similar to a crime done in 1932 by Bruno Hauptmann. Bruno kidnapped the baby of Charles and Ann Lindebergh and left a note that held a ransom of 50,000 to get their child back. The ransom was paid but the child was never returned, two months later the child ws found dead in the woods. Bigger has a ransom for 10,000 but has no intentions of returning mary since she is already dead.
Bruno Hautmann and blindness... blind to the fact that he would eventually get caught, and when the parents for thinking everything would be okay after they paid.
Why wouldn't bigger get someone to write the letter for him and not in his own handwriting?
What is Bigger going to do if he succeeds in getting the money, will he still work for the Dalton's or willl he leave?
