Feds: $4.8M more bilked from firm

Updated: February 13, 2013 6:09AM



Already charged with bilking one of Chicago’s largest and oldest law firms out of nearly $1 million, a former top executive at Mayer Brown has now been accused of teaming up with an accomplice to steal nearly $5 million more.

David Tresch, 51, of Itasca, was fired from his job as chief information officer at Mayer Brown in June following an internal investigation.

First charged in August with stealing $850,000 through false billing to an IT contractor, Tresch is now accused of conspiring over a seven-year period starting in 2004 with fellow Itasca resident Nicholas Demars, 57, to share $4.8 million falsely billed to Mayer Brown.

Under the scheme, Demars’ business, NS Mater, billed Mayer Brown for contract employees and technology it didn’t provide, a grand jury indictment alleges. Tresch approved the payouts to Demars, who later kicked back cash to Tresch and his wife, it’s alleged.

Prosecutors want to force the forfeiture of the stolen money, as well as both men’s homes, Demars’ Chicago condo in Chicago, his residence in Lake Geneva, Wis., and more than $225,000 seized from Tresch, along with his camping trailer, a van, and a luxury car.
