Naperville Chief of Police Robert Marshall has announced his retirement. The longtime Naperville employee will wrap up his tenure with the city on July 2.

Marshall served as chief of police beginning in 2012, but has been with the city of Naperville for 44-years. His law enforcement career began in 1975 as a Will County Sheriff's Deputy until he joined the Naperville Police Department in 1977. He retired form police work in 2005 and took a job as assistant city manager before becoming chief of police in 2012.

Marshall is credited with enhancing police and community relations and encouraging a culture of transparency and accountability.

For a career-end accomplishment, Marshall, along with the Will County State's Attorney's Office, recently announced charges, and an arrest, in a 49-year-old case involving the murder of a Naperville girl. The murder happened in 1972, just three years before Marshall began his law enforcement career. 

Marshall says that the Naperville Police Department is well positioned for continued success.

Editor's note: An earlier version of this story incorrectly said that Marshall began as deputy in 1957. It has been changed to say 1975. We regret the error.
