A federal jury convicted a D.C. police officer of tax fraud after authorities said he failed to file individual income tax returns for eight years.

The officer, Ishmeal Heru-Bey — formerly known as Jamal A. Adams — did not file his tax returns from 2005 to 2012. Heru-Bey, of Glenarden, Md., was also found guilty of improperly claiming deductions for the cost of buying his uniform and other unreimbursed employee expenses while on paid administrative leave.

After a five-day trial, the jury Tuesday convicted Heru-Bey of trying to obstruct the Internal Revenue Service.

Heru-Bey faces a maximum of three years in prison and a $250,000 fine. A D.C. police spokesman said Heru-Bey, who was hired in 2002, was last employed by the department in August.

To prevent D.C. police from withholding federal income taxes from his wages, authorities said Heru-Bey submitted three false W-4 forms. He falsely claimed on the forms that he was exempt from income-tax withholding.

After he was indicted on tax charges in March, authorities said Heru-Bey filed false individual income tax returns for years 2011 and 2014 on which he fraudulently claimed deductions relating to unreimbursed employee expenses — including expenses for uniforms, dry cleaning, vehicle mileage and meals.

The government introduced evidence that proved the officer was not entitled to claim these expenses because he was on leave during those years.

Authorities said the resulting tax loss for the years 2005 through 2011 and for 2014 exceeded $90,000.

Heru-Bey’s sentencing is scheduled for Jan. 7.
