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 SCCPDCL has expanded its services to include biology/deoxyribonucleic acid (DNA) and firearm and toolmark examinations.
