This is what white collar criminals do after prison by Daniel Bukszpan @FortuneMagazine March 10, 2015, 5:53 AM EDT E-mail Tweet Facebook Google Plus Linkedin Share icons Congratulations, L. Dennis Kozlowski! Your years of imprisonment and penal supervision have come to an end and you’re a free man, your debt to society fully paid. Now go out there and be somebody! For those who have forgotten, Kozlowski was CEO of the security systems giant, Tyco International, and the position allowed him to live large. According to The New York Times, this meant a $6,000 shower curtain in his home and a $2 million birthday bash for his second wife, featuring a sculpture of Michelangelo’s “David” that dispensed vodka from an appendage in its bathing suit area. It all ended in June 2005, when he was found guilty of 22 counts of conspiracy, falsifying business records, grand larceny and securities fraud and sentenced to 8 1/3 to 25 years in prison. But that’s all in the past now, and Kozlowski must now undertake the herculean task of figuring out where he goes from here. Luckily, he’s not the first white collar figure to endure a stay in the pokey, and he has several examples of others who went to prison, did their time, and emerged to write their lives’ next chapter. Fortune presents a few of them here, in the hope that they may give him some ideas.
