Two attorneys were convicted late Wednesday in a scheme to fraudulently collect referral fees on tax shelters designed and marketed in conjunction with the defunct law firm Jenkens & Gilchrist.

John B. Ohle III, who worked as a supervisor in the Chicago office of Bank One’s “innovative strategies group” and helped design the shelters, was found guilty of wire and tax fraud conspiracy and two counts of tax evasion following a three-week trial before Southern District Judge Jed S. Rakoff.
