San Francisco Sheriff's deputies back up the San Francisco Police as needed, as well as make arrests for criminal and vehicle-code violations while performing their duties. The Denver Sheriff Department maintains the county correctional facilities as well as court functions. Law enforcement and investigations are the responsibility of the Denver Police Department. Denver's sheriff is appointed by the mayor, and serves as the sworn head of the sheriff department. Denver has had deputy sheriffs since the creation of the City & County of Denver in 1902, however the Denver Sheriff Department current organization was not established until 1969, consolidating all of the sheriff's functions under one management structure. The Denver Sheriff is, along with Broomfield's, an anomaly within the state. In every other county, the Sheriff is an elected official and is the chief law enforcement officer of his county. Connecticut abolished county sheriffs in 2000 by Public Act 00-01. All civil-process-serving deputies were sworn in as state marshals, and criminal special deputies were sworn in as judicial marshals. Constables remain municipal officers governed by their respective town or city. A few towns have local sheriffs that primarily perform process serving duties and may act as a sergeant at arms for town meetings. Prior to the abolition of county sheriffs in 2000, duties of sheriffs in Connecticut were limited to process serving, court bailiffs, and executing search and arrest warrants. Other law enforcement duties, such as emergency response, highway patrol and traffic enforcement, and maintaining public order were left to municipal police departments or constables or the Connecticut State Police in places where no local police agency exists. The first Constitution of Delaware in 1776 made the sheriff a conservator of the peace within the county in which he resides, either New Castle, Kent, or Sussex. The sheriff was, and still is, chosen by the citizens of each county at the general elections to serve a four-year term. Per Title 10, Chapter 21 of the Delaware Code, the Sheriff is an officer of the court. Responsibilities include processing orders of the court system; summoning inquests, jurors, and witnesses for the courts; and, conducting execution sales against personal and real estate property. County Sheriffs and their regular appointed deputies also take into custody unincarcerated persons immediately upon conviction of an imprisonable offense and convey them to the appropriate correctional facility to serve their terms. The County Sheriffs and their deputies do not engage in typical law enforcement; their primary role is to provide enforcement services for the courts. Typical law enforcement, such as the enforcement of motor vehicle laws, investigation of crimes and routine policing patrols are performed by state, county, and municipal (town or city) police forces.
