Question: In what state is the police department that dealt with the Wayne Williams child murders located?
Context: The Atlanta Police Department is the law enforcement agency of the city of Atlanta, Georgia, U.S. The Evidence of Things Not Seen is a 1985 nonfiction book by James Baldwin about the Wayne Williams Atlanta child murders of 1979-1981.  The title is a reference to the definition of faith from the Biblical Letter to the Hebrews 11:1. Wayne Bertram Williams (born May 27, 1958) is an American serial killer who was tried, convicted, and sentenced to life imprisonment in 1982 for killing two adult men.  After his conviction, the Atlanta Police Department announced that Williams was responsible for at least twenty-three of the twenty-nine Atlanta murders of 1979–1981, also called the "Atlanta Child Murders".  Williams continues to maintain his innocence. The Municipal Integrated Emergency Response Team (MIERT) was an emergency response unit formed as a joint venture of police agencies in the Lower Mainland of British Columbia, Canada.  It was formed in 2006 and is composed of members of the Delta Police Department, the Abbotsford Police Department, the New Westminster Police Service, and the Port Moody Police Department.  In 2013 the MIERT was disbanded and the Abbotsford Police Department formed its own Emergency Response Team.  The remaining services have decided to either combine or contract their teams with the Vancouver Police Department (Delta Police Department, Port Moody Police Department) or contract with the Royal Canadian Mounted Police (New Westminster Police Service). Who Killed Atlanta's Children?  (also known as Echo of Murder and Unanswered Questions) is a TV movie about the Atlanta child murders starring James Belushi and Gregory Hines.  It was directed by Charles Robert Carner and first aired on Showtime on July 16, 2000.  This movie projects a conspiracy theory about the murders: that they were committed by the Ku Klux Klan, who then framed Wayne Williams. The Atlanta Child Murders is a TV miniseries that aired on February 10 and 12, 1985 on CBS.  Inspired by true events, the miniseries examines the so-called "Atlanta child murders" of the late 1970s and early 1980s. The Charlotte-Mecklenburg Police Department is the police department of the City of Charlotte & Mecklenburg County, North Carolina, US.  With 1,849 officers and 473 civilian staff as of 2014, covering an area of 438 sqmi with a population of nearly 900,000, it is the largest police department between Washington D.C. and Atlanta, Georgia.  The CMPD is unique in that it was formed in 1993 with the merger of the former Charlotte City Police Department and the Mecklenburg County Rural Police Department.  Mecklenburg and neighboring Gaston County were the two counties out of the state's 100 counties to have county police in addition to the sheriff's offices.  County police perform law enforcement tasks in the county with police powers anywhere in the county just like the sheriff, but the sheriff primarily handled the courts and jails.  The North Carolina General Assembly approved legislation combining the two agencies.  They are by statute "county police" in that they have jurisdiction anywhere in Mecklenburg County.  However currently, the CMPD does not have any response areas outside Charlotte but within Mecklenburg County.  The unique status of this situation makes the CMPD "metro" police, and the City of Charlotte has no municipal police department. The Charleston Police Department, or CPD, is the official municipal police force for the City of Charleston, West Virginia.  The Charleston Police Department is currently the second largest police department in the state of West Virginia, while being the largest municipal/city police department in the state.  As of 2008, Charleston Police currently has 184 sworn officers, 2 Animal Control Officers, and 29 civilian employees.  The Charleston Police Department has an organization of several different divisions, including a Patrol Division, Traffic Division, SWAT, Bicycle Unit, K-9 Unit, Community Policing & School Services Division, SEU or Special Enforcement Unit, and CID or Criminal Investigation Division.  The current Chief of Police is Brent Webster. The Atlanta murders of 1979–1981, sometimes called the Atlanta Child Murders (although several of the purported victims were adults), were a series of murders committed in the American city of Atlanta, Georgia, from the middle of 1979 until May 1981.  Over the two-year period, at least 28 African-American children, adolescents and adults were killed.  Wayne Williams, an Atlanta native who was 23 years old at the time of the last murder, was arrested for and convicted of two of the adult murders, and sentenced to two consecutive life terms.  Police subsequently have attributed a number of the child murders to Williams and closed the cases, although he has not been tried or convicted in any of those cases. The Cambridge Police Department is the municipal police department for the city of Cambridge, Massachusetts, in the United States.  Formally organized in 1859.  with the appointment of John C. Willey as the first Chief of Police, the Cambridge Police Department was then manned by only 16 officers.  The Cambridge Police Department moved its headquarters location on December 8, 2008.  The police department is now located in the Robert W. Healy Public Safety Facility at 125 Sixth Street in the neighborhood of East Cambridge, leaving their Central Square location after 135 years.
