Analysis at the crime scene in Villisca by special agent and "fingerprint expert" M. W. McClaughry of Leavenworth Prison indicated the killer was left handed. Later, upon observing George Kelly chop wood, it was found that the reverend was left handed as well. I bring this up because the investigators on both the Ardenwald and Rainier crimes scenes came to the conclusion the killer (or killers) was left handed. There are many things you have to worry about as a lefty. Manual can openers are an affront to your existence, golf clubs cost double and you're only allowed to play 1st base or pitcher in baseball. But those are minor complaints really.
