The DeKalb County Courthouse is located in the county seat of DeKalb County, Illinois, U.S., the city of Sycamore. The Classical Revival structure sits on a square facing Illinois Route 64 as it passes through the city. The current courthouse was constructed in 1905 amid controversy over where the courthouse and thus, ultimately, the county seat would be located. The current building is the third structure to bear the name "DeKalb County Courthouse." DeKalb County's Courthouse still serves as the county's primary judicial center and is a contributing property to the Sycamore Historic District. The district joined the National Register of Historic Places in 1978. As the county's primary courthouse for over 100 years, the site has been host to many trials, including prominent murder cases. The building is cast in the Classical Revival architectural style and contains elements common to that style. Stained glass, columns and a pediment are among the more noticeable features at a glance. The rear facade of the building is designed to resemble a temple and also features stained glass windows. A stone porte-cochere covers the rear driveway. Inside the building's third floor courtroom is more stained glass, in the form of a skylight. During the early 1980s the made-for-television movie Will: G. Gordon Liddy filmed scenes in the DeKalb County Courthouse's courtroom.

Maria Elizabeth Ridulph (March 12, 1950 – c. December 1957) was a seven-year-old girl who disappeared from Sycamore, Illinois, on December 3, 1957. Her remains were found almost five months later in a wooded area near Woodbine, Illinois, approximately 90 miles (140 km) from her home. Maria was last seen by her friend on her neighborhood corner of Center Cross Street and Archie Place with an unknown man in his early twenties who called himself "Johnny".The case, which was well known in the Chicago area, was one of the oldest cold case murders in the United States to be presumably solved. Jack McCullough, who under his former name John Tessier had been a neighbor of the Ridulph family, was convicted for her murder in September 2012. However, in March 2016, the DeKalb County State's Attorney announced that a post-conviction review of available evidence showed McCullough could not have been present at the place and time of Maria Ridulph's likely abduction. McCullough was released from prison on April 15, 2016, and the charges against him were dismissed on April 22, 2016. McCullough was declared innocent of the crime by the DeKalb County Circuit Court on April 12, 2017.
