EXETER, Neb. (AP) — A couple who used to run a gun shop in Exeter have been convicted on tax charges.

Online court records say 46-year-old Robert Androyna and 42-year-old Hope Androyna pleaded no contest on Tuesday to failing to pay sales tax and evading income tax. Prosecutors dropped three other felony charges filed against both Androynas in exchange for their pleas.

The Nebraska Department of Revenue says in court filings that the Androynas took in $3.78 million from their Exeter Arms business from 2009 through 2012. That included nearly $200,000 in local and state sales taxes that the department says they didn’t send to the state.

The state says the Androynas didn’t report profit, income or wages from their business until October 2013, when the Revenue Department was already investigating them.
