My top two ransom note mysteries:

1.) Why was the writer of the note seemingly unconcerned about getting caught and unafraid of his handwriting being identified?

2.) Why does it appear that the writer either went back and added little curly-q's on the top of the a's or did it as he went along?

If one pictures someone with a drug-induced ego enhancement mimicking Patsy's handwriting, it would answer both questions.

Bonus question number 3:

Why was the ransom note writer unconcerned about having an alibi?
