A second attorney and two tax professionals have been indicted in the $1 billion Garza tax shelter scheme. Attorney and CPA Kevin McDonnell and CPA James Richardson, co-owners of tax preparation and accounting firm McDonnell Richardson, P.C., were added to the case in a superseding indictment recently filed. The pair are charged with one count of conspiracy to defraud the United States, one count of conspiracy to commit wire fraud, and five counts of assisting in the preparations of fraudulent tax returns. Craig Fenton, a tax manager at McDonnell Richardson, was indicted on the same charges. The alleged mastermind of the scheme, attorney Joseph Garza, was previously indicted on 18 counts of wire fraud, one count of conspiracy to commit wire fraud, and 22 counts of aiding and assisting in the preparation of fraudulent income tax returns. The superseding indictment added a charge of conspiracy to defraud the United States.
