A former Spector Gadon & Rosen associate who resigned from the bar in 2012 was charged Thursday for allegedly stealing more than $500,000 from his former firm’s trusts and estates clients.

Gomer Thomas Williams III, 54, was charged in an information by the U.S. Attorney for the Eastern District of Pennsylvania with stealing $503,361 from four clients through his role as either trustee or administrator of those clients’ trusts or estates, according to the information, which also alleged Williams overbilled clients. The alleged theft took place between 2007 and 2012.
