Katherine Kelly, a.k.a. Grandma Awesome, the fingerprint-less 76-year-old who has, prosecutors say, been arrested 73 times and used multiple aliases in a criminal career spanning 40 years, pleaded not guilty yesterday to pickpocketing at an Upper West Side Fairway. She then "hobbled" back to prison where she showed her fellow inmates how to burn off their fingerprints, break into a bank, and make a rope ladder out of sheets. [NYP]
