   Q: How do I need to package evidence intended for the latent evidence unit? 

       A: See Evidence Submittal section here.

 

   Q: Can I email known prints collected for submission to the Latent Evidence Unit?  

       A: No.  Due to current in-house policies regarding evidence submission, known prints may not be emailed for submission to be used in comparison to latent prints.

 

   Q: Does the latent evidence unit handle submitted fingerprint cards used for background checks?  

       A: No.  The OSBI Ten-print Unit handles this.

 

   Q: How should a latent print card be documented?    

       A: All latent lift cards need to include: 

               1) Date the lift was made

               2) Officer’s initials

               3) A description of the location or item the prints were lifted from

          Note:  Please understand that we require such documentation to protect the integrity of the evidence and its value to the court. 

 

   Q: What is OSBI AFIS?    

       A: The OSBI Automated Fingerprint Identification System (OSBI AFIS) is the state system used for searching latent fingerprints and palm prints against the state 

             repository of known prints.  The state repository for prints includes criminal and civilian submitted known fingerprints and palm prints.

 

   Q: What is FBI NGI?     

       A: The FBI Next Generation Identification (FBI NGI) is the FBI's system used for searching latent fingerprints and palm prints against the national repository of known 

             prints.  The national repository for prints includes criminal and civilian submitted known fingerprints and palm prints.

 

    Q: Is there a footwear and/or tire impression database?     

       A:  No.  

             Known footwear (the actual shoe/boot is preferred) must always be submitted with unknown impressions.  

             Known tire impressions (inked tire impressions are preferred) must always be submitted with unknown impressions.

 

              Note:  Please, never remove a tire from a vehicle and submit it.

 

   Q: What are latent prints?   

       A: Latent prints are "hidden" prints that usually need some kind of processing technique in order to view them.  For more information see the Impression Evidence

   Information page here.

 

   Q: What are inked prints?    

       A: Ink is rolled on the fingers, and fingers are then rolled on a fingerprint card leaving a unique pattern, similar to pressing a stamp down on paper.  For more 

            information see the Impression Evidence Information page here.

 

   Q: Is a fingerprint REALLY permanent and unique to each individual?   

       A: Yes.  Friction ridges form during the 3rd - 4th month of fetal life and persist through death until skin decomposition.  Friction patterns and shapes differ 

             between individuals, including twins.  "The basis for this fact may be found in the principle of biological variation, proposed by Charles Darwin, that no two living 

             things are ever exactly alike."  --Scott's Fingerprint Mechanics, Robert D. Olsen, Sr.

 

   Q: How do you become a latent print analyst in the Latent Evidence Unit?    

       A: The OSBI requires a bachelor's degree from an accredited college or university.

 

   Q: If I am a student and interested in a practicum with the Latent Evidence Unit at the OSBI, where can I obtain information on the program?    

       A:  For more information on the program, please go to the main laboratory FAQ's.

 

   Q: Where do I look for jobs that are open at the OSBI?
