Big law firms spend a lot of money on posh decor and office supplies. So perhaps it’s not surprising that sometimes those same firms become victims of dishonest employees in cahoots with the outside vendors who keep the offices well-stocked and looking good.

Over the past few years, The Am Law Daily has chronicled the exploits of a former Wilson Sonsini Goodrich & Rosati purchasing specialist who in 2009 was charged and later pleaded guilty to an alleged $1 million scheme involving fraudulent orders of tab dividers. In 2014, a former Mayer Brown chief information officer received a 27-month prison sentence over his role in a $4.8 million fraud related to phony invoices submitted by an information technology vendor.
