Welcome to the DuPage County Forensic Science Center


About our Laboratory

The DuPage County Crime Forensic Science Center (FSC) is located in Wheaton, Illinois, approximately 30 miles west of Chicago. Since May 1st, 1971, the citizens of DuPage County have benefited from the laboratory services provided by the Sheriff's FSC, which are made available to all law enforcement agencies in the county.  In 2006, the DuPage County Sheriff’s Office earned the prestigious international ISO 17025 certification for forensic testing laboratories through the ANSI-ASQ National Accreditation Board.


Our Mission

The mission of the DuPage County FSC is to provide quality and timely forensic science services to the criminal justice system of DuPage County.  The laboratory has three sections:  Forensic Chemistry and Microscopy, Criminalistics and Forensic Biology/DNA which offer analysis in the disciplines of Drug Chemistry, Latent Prints and Forensic Biology/DNA.
