The AP's lede:
"Authorities in Arizona have arrested a man who police believe severed his finger while slashing his neighbor’s car tires after an argument.
Maricopa Police Department spokesman Hal Koozer said Kevin Johnson was arrested and identified as the owner of the finger found on his neighbor’s driveway, the Casa Grande Dispatch reported Wednesday."
"Show me your hands!" takes on a new meaning with this digit-less dope. Also, the police didn't need to run a fingerprint check since Johnson left a trail of blood right to his home. D'oh!
