The New Albany Police Department is down to three sergeants after Jillyan Will resigned Sept. 22, said Chief Greg Jones.

Her resignation letter, which was dated Sept. 22, did not state a reason. She resigned the same day as her letter, said city spokesman Scott McAfee.

Will was New Albany's first female officer and joined the department in 2015.

In April, she became a sergeant, receiving an $87,201 annual salary and total benefits worth about $42,500.

She was promoted to sergeant at the same time the police department hired former Hilliard Division of Police officer Curtis Baker, bringing the roster of sergeants to four. Kris Daniels and Garrett Fernander are the other sergeants; Ed Burton, a sergeant at the department since 1990, retired May 5.

With Will's departure, New Albany has 16 officers, three sergeants and the chief, McAfee said. The administrative sergeant, Daniels, will cover some of the patrol shifts for which Will was responsible, he said.

"All of our officers are trained and skilled in communicating with men, women and children of all ages," McAfee said. "We also have a DARE officer and a school resource officer stationed on the school campus throughout the school year to provide added security and build lasting relations."

The department won't take any unnecessary delays to fill Will's position, although it has no timeline to replace her, Jones said. Historically, the department has looked internally and externally to fill sergeant positions, but most have been internal promotions, he said.

The city also plans to add one or two more officers to the duty roster, McAfee said.
