Since January, Dennis Kozlowski, the once wedding band guitarist who became CEO of Tyco (and later embezzled millions from the conglomerate in order to sustain a hedonistic lifestyle that included gold-plated everything and a notorious Sardinia party featuring an ice statue of David that peed vodka), has been living in a prison on West 110th Street. There, the man Time magazine dubbed the third most crooked CEO (after Bernie Madoff and the Enron guys) has been doing some financial consulting for a nonprofit that works with ex-cons. And, when he needs a break, Kozlowski gets weekly furloughs that allow for jaunts to nearby Central Park.
