Forensic science is the application of science to criminal and civil laws and plays a vital role in the criminal justice system. The St. Mary’s County Sheriff’s Office Crime Lab is located at District 3 Station in California and is currently staffed by four crime lab technicians, a fingerprint technician and a lab supervisor of the crime.

Technicians are available to answer calls 24 hours a day, 365 days a year. Crime lab technicians are specially trained in various aspects of forensics and all hold at least a bachelor’s degree in physical science. Technicians intervene at crime scenes to identify, document, collect and preserve evidence.

When not in the field, technicians are busy in the lab processing evidence. The St. Mary’s County Sheriff’s Office Crime Lab maintains a high standard of quality work and seeks to continually advance the lab with modern technology. Recently, the laboratory acquired the most advanced image capture system in the world, the Full Spectrum Imaging System (FSIS).

FSIS uses different wavelengths of light and filters to allow technicians to view and digitally capture high-resolution, real-time images of evidence otherwise invisible to the naked eye, including: altered documents, urine, semen, saliva, blood, GSR, dye-stained fingerprints and erased serial numbers. Additionally, technicians process latent fingerprint evidence and touch DNA, perform presumptive testing, test confiscated firearms for NIBIN entry, obtain and review video surveillance, extract digital media and much more. .

“The St. Mary’s County Sheriff’s Office Crime Lab is a dedicated and professional team,” said Capt. Edward Willenborg, Commanding Officer of the Criminal Investigations Division.

“Our Criminal Investigations Division detectives could not complete their investigations without the exceptional work of our Crime Lab.”
