WILMINGTON, Ohio — Wilmington Police Chief Duane Weyand will resign at the end of the month, Mayor John Stanforth announced Monday.

Weyand had been placed on administrative leave in January pending investigations into alleged department misconduct. An announcement about his resignation states that Weyand and city officials signed a memorandum of understanding Monday, and the agreement "does not include any monetary settlement exceeding that allowed by city policy."

"While the chief is not the subject of a criminal investigation, the city will continue to review existing policies and procedures to understand the challenges and inconsistencies in the department," Stanforth said in a written statement.

Last month, one of the officers under investigation, Anthony Mitchell, also resigned. Stanforth said that Mitchell was accused of failing to follow departmental rules and procedures, and resigned after a pre-disciplinary hearing.

"Our actions will protect the integrity of our police department and support the important work they do for all of us," Stanforth said last month. "We rely on the hard work and good faith of all the men and women who work for the City of Wilmington, and as disappointed as I am in the actions of a few, I’m satisfied that we are addressing the issues carefully and expeditiously."

All department employees under investigation have either resigned or been placed on administrative leave until the conclusion of the investigations, Stanforth said.
