Didn't that Swiss rascal, William Tell, use a crossbow?  Maybe a descendant slipped a gear and is out shooting Austrian Dukes again.

In the mid 80's my family was stationed in Spain and my dad had to sit on the jury for a servicemember who killed his two live-in girlfriends with a crossbow. The coroner had to examine medieval medical texts to validate that was what the murder weapon was. Then the idiot threw the crossbow and used bolts in a field where some gypsies found it, saw the blood all over the bolts (He only had two, but used the same one twice) and sold it to the police, sealing the case. Who drives along multiple kilometers of beach, over three bridges, then throws away a bloody murder weapon in a field?
