History of the Sheriff’s Office

In 1902, voters approved the creation of Adams County, which had previously been part of an enormous Arapahoe County. The county was named after Alva Adams, a popular former governor in office at the time of this election.

Brighton was chosen as the permanent county seat in an election held on November 8, 1904. As was befitting a new and prosperous county, a new courthouse was built at 4th and Bridge Street in 1906. That building still stands as Brighton City Hall.

The first meeting of the Adams County Board of Commissioners was held on December 4, 1902, in Brighton. The first three commissioners were Fred P. Watts, a former Arapahoe County Commissioner from the Brighton district, John Benbow, and Wilson R. Smith, both appointed by the then-governor of Colorado, James B. Orman. Smith served as county commissioner for only one month before resigning; Edward Fitzpatrick replaced him.

During this meeting, the commissioners accepted Governor Orman’s appointments for county officials: Christopher E. Lunney, county clerk; Charles R. Cook, assessor; George M. Griffin, treasurer; Martin R. Bromley, sheriff; Rice Means, county judge; and Martin I. Dowling, surveyor.
