The first DuPage County Jail was built in 1868. The jail was part of the courthouse and the total cost for the entire building was $20,000. The second jail was built in 1896. The jail was only built to house eight inmates. It was expanded to hold 48. The third was built in 1959. It cost $960,000 and held 85 inmates. The fourth was built in 1983. The cost was $14 million and held 310. This is the current jail and had an addition built in 1995. The jail now holds a total of 825 inmates.

On September 27, 1929, Chief Deputy Gordon Leonard and Deputy Sheriff Ralph Hoy were transporting a prisoner. The patrol car went off the road for some reason and overturned. Both deputies died in the accident.

On February 15, 2019, DuPage County deputies responded to shots fired at the Henry Pratt Company in Aurora. The Federal Bureau of Investigation, Bureau of Alcohol, Tobacco, Firearms, and Explosives and the United States Marshals Service also responded to help. Gary Montez Martin had been fired, which caused him to start shooting. He was known to be violent. In DuPage County alone, he had been arrested six times, including charges of domestic violence. He had been convicted of felony aggravated assault in 1995 in Mississippi. He had also been arrested in Oswego, Illinois for disorderly conduct and damage to property.

The Aurora Police Chief said he was not supposed to have a firearm anymore because of this. Even though he had been convicted of a felony in 1995, Martin was able to get a Firearms Owners Identification card in Illinois in 2014. Law enforcement says that was because there was no check on fingerprints. Later, when he applied for a conceal carry permit, his felony was found. A letter was sent canceling the FOID card and ordering him to turn in the firearm. He never did.

During the time Martin was shooting, he killed the human resources manager, a human resources intern, the plant manager, a mold operator, and a forklift operator. Another plant employee was injured. The police arrived and a firefight started. Four members of law enforcement were shot, one was hit by shrapnel, and another was injured in another way. No law enforcement was killed. During the shootout, Martin was killed.
