                    The OSBI Latent Evidence Unit (LEU) is a section of the OSBI Criminalistics Division housed in the Forensic Science Center in Edmond, Oklahoma.  


          The LEU specializes in latent print, footwear, and tire impression collection, examination, development, and comparison.


          Services provided by the LEU latent print examiners include:

                   × Comparing unknown impressions to known impressions

                   × Laboratory processing of evidence

                   × Crime scene processing

                   × Collecting inked impressions of deceased individuals


          A few of the tools utilized in accomplishing these tasks include the Automated Fingerprint Identification System (AFIS), the Federal Bureau of Investigation Next Generation Identification (NGI), digital imaging equipment, and various chemical and physical development techniques.


          All criminalists at the OSBI Forensic Science Center are tasked with the responsibility of providing quality forensic science services in a timely manner to the criminal justice community. 


           The goal of all criminalists involved in impression evidence development/comparison is to provide the most accurate and timely analyses possible.
