BANGOR, Maine — Two longtime city police officers are being promoted, Lt. Paul Edwards said Tuesday in a news release.

Sgt. Catherine Rumsey, the department’s public information officer, will be promoted to the rank of lieutenant — the first female officer to achieve that rank as well as the first female sergeant, Edwards said.

In her new role, Rumsey will oversee the management of the department’s evening and overnight patrol crews.

Rumsey has been with the Bangor Police Department since 1996. Before that, she was a police officer at the University of Maine and for the Minot Police Department in North Dakota.

During her career with the Bangor Police Department, Rumsey has been assigned to the Detective Division as domestic violence investigator and has served as a certified polygraph examiner and a nationally recognized RAD instructor. She has been the department’s public information officer since October 2013.

Detective Timothy Cotton will be promoted to sergeant, Edwards said. Cotton will be assigned to the evening and overnight patrol crews.

Cotton joined the Bangor Police Department in 1997. Before that, he was a police officer in Hampden for nine years. Cotton has been one of the department’s lead homicide investigators since 2002. He also has worked as a DARE officer and as a Bangor High School liaison officer.

Cotton is a nationally recognized polygraph examiner, crisis negotiator and firearms instructor.
