The 4th Judicial District Attorney’s Office was established in 1876, when the first legislature to convene carved out a 4th Judicial District from the three that had existed since Colorado became a territory in 1861. Initially, the 4th Judicial District was enormous in geographic scope, encompassing 12 of the state’s original 26 counties. With the constant growth of the state’s population, and the eventual addition of 18 more judicial districts, the 4th District has gradually been pared down to its present geographic dimension, consisting of El Paso and Teller counties with a joint population of 723,000.
