Criminalistics Laboratory Division


The St. Charles County Police Department Criminalistics Laboratory (SCCPDCL) provides state-of-the-art forensic analysis of evidence submitted from law enforcement agencies in and around St. Charles County.

The SCCPDCL was established in 1988 in response to the need for a crime laboratory to serve the law enforcement community of St. Charles County. Initially set up to analyze only drug cases, the SCCSDCL has expanded its services to include fire debris analysis, biology / deoxyribonucleic acid (DNA), blood ethanol, serial number restorations, and firearm functionality examinations.

Current Location and Staff

The SCCPDCL moved into its current location in O'Fallon in April 2005. This facility has approximately 5,300 square feet dedicated to crime laboratory functions. In May 2008 the SCCPDCL became accredited by the American Society of Crime Laboratory Directors - Laboratory Accreditation Board (ASCLD/LAB) under their Legacy accreditation program.  In 2013, the laboratory was awarded ASCLD/LAB-International accreditation. 

The SCCPDCL analyzes approximately 2,000 cases per year and is staffed by 4 full-time scientists with combined forensic laboratory experience of over 60 years.
