Former Spector Gadon & Rosen attorney Gomer “Tom” Williams III was sitting in his car with a shotgun Oct. 1, 2012, he told a federal judge Monday, about to end his life over what he said was overwhelming guilt from stealing more than $500,000 from clients.

Williams’ wife Coleen, who has worked as a paralegal at Cozen O’Connor for 25 years, talked her husband out of pulling the trigger and then made a phone call to her firm’s chairman, Stephen A. Cozen. Within an hour, Cozen O’Connor white-collar defense attorney William J. Winning was involved and soon heard the story of Tom Williams’ five-year scheme of taking money from his trusts and estates clients’ accounts.
