— The Janesville Police Department has named a new deputy chief and a new lieutenant.

John W. Olsen, a former lieutenant, was promoted to deputy chief Monday after the position had been open all year.

Terrence E. Sheridan, a former sergeant, was promoted to lieutenant to replace Olsen.

“Both of these officers are committed, talented and well respected by both the community and police department,” Chief Dave Moore said. “They will provide leadership for the police department for many years to come.”

Olsen has been with the department for 23 years. He has a bachelor’s degree in public administration from Upper Iowa University. He also graduated from the Northwestern University School of Police Staff and Command.

Olsen has been in charge of the street crimes unit and K-9 unit. He has supervised snipers on the SWAT team. He also has worked in narcotics enforcement and special operations.

Olsen replaced former Deputy Chief Steve Kopp, who retired in December. Olsen’s promotion was not subject to the approval of the Janesville Police and Fire Commission.

The deputy chief position remained open all year to save money. Delaying promotions is common to help the budget.

Sheridan is a 19-year veteran of the department. He has a bachelor’s degree in public administration from Upper Iowa University. He has been a patrol officer and identification officer. He also has been a field training coordinator and SWAT team leader.

The Janesville Police and Fire Commission approved Sheridan’s promotion.

An officer was promoted to sergeant in April to replace Sheridan. Sgt. Mark Ratzlaff got the position.

Ratzlaff has been with the department for 14 years. He has a bachelor’s degree in sociology from UW-Whitewater, with a minor in criminal justice. He also has experience as a training officer, instructor and member of the narcotics team.

The department also is hiring four new police officers, Moore said. It had 288 applicants, and 40 of them will have an opportunity to interview.
