Laboratory Division

In processing more than 200,000 pieces of evidence a year, BCI’s Laboratory Division employs the highest standards of care and most advanced technologies to help law enforcement throughout Ohio bring criminals to justice, exonerate the innocent and find answers for grieving families.

The forensic scientists at BCI are committed to providing accurate, timely analysis of evidence to all of Ohio’s law enforcement agencies. The scientists specialize in examining physical and biological evidence in multiple forensic disciplines, listed at right.

Tools used by the Laboratory’s forensic scientists include chemical tests, digital photography, comparative microscopes, video spectral comparators, scanning electron microscopes, X-ray fluorescence spectrometry, capillary electrophoresis instrumentation, gas chromatography/mass spectrometry and Fourier transform infrared spectrometry. Scientists in the DNA and CODIS units are assisted by lab robotics that speed turnaround times, reducing from days to hours the time needed to conduct certain tests.
