Convicted Sheriff Will Lewis was found guilty on one count of misconduct of a public officer and not guilty on a separate misconduct in office charge Thursday night.

He was sentenced to one year in prison at a hearing Friday morning.

According to indictment documents, "Lewis committed the crime of misconduct of a public officer by performing acts of official misconduct, habitual negligence, corruption, fraud, or oppression."

Lewis, who is accused of using public resources to carry out an adulterous affair with his former assistant, Savanah Nabors, was convicted by a jury in Greenville County last night.

The jury also found Lewis not guilty of misconduct in office. That charge claimed "As Sheriff, William D. Lewis willfully and dishonestly failed to properly and faithfully discharge the duties of his public office imposed on him by law."

Per state law, Gov. Henry McMaster will remove him from office immediately.

A special election to fill the post will be held in several weeks, and interim Sheriff Johnny Mack Brown will remain in the seat until a new sheriff is sworn in.

Lewis will be sentenced at 10 a.m. Friday. The verdict came after four days of trial in Greenville County. The jury deliberated for about four-and-a-half hours.

Under state law, misconduct in office is punishable by up to a $1,000 fine, one year in prison and automatic removal from office.

Lewis' attorney, Rauch Wise, asked Judge G. Thomas Cooper to allow Lewis to go home for the night after the verdict was read, saying there was no flight risk and citing safety concerns for the former sheriff to spend a night in jail.

Cooper allowed it over objections from 16th Circuit Solicitor Kevin Brackett.

Brackett said Lewis "shouldn't be treated differently than anybody else in this situation."

"Mr. Lewis, if you're not in court tomorrow, all hell will reign down on you," Cooper said.

After the verdict, Lewis declined to speak. Wise addressed reporters following the verdict.

"I think they had trouble interpreting the difference between the two (charges). It just seemed pretty logical to me — it's an ambiguous statute," Wise said.

Wise said he and Lewis were disappointed in the verdict and felt the misconduct charges against him overlapped enough that the verdict should have been the same on both charges.

"We thought that we established what we needed to in this case to prove it was guilty or not guilty on both of them, and the jury disagreed with us," Wise said.

Brackett expressed his gratitude to the jury.

"They were a conscientious group," he said.
