Specialized Forensic Biology Unit


The Specialized Forensic Biology Unit (SFBU) specializes in Property Crimes and Cold Cases.  With the hundreds of major crimes that happen each year, it was easy to give those cases prioritization.  The SFBU unit was created in 2014 to give property crimes and cold cases the attention they needed.  

The SFBU is a discipline of the OSBI Criminalistics Services Division housed at

Forensic Science Center in Edmond, Oklahoma 



Property crimes consist of crimes that are non-violent such as burglaries and auto-theft.


Specific requirements of evidence submittal for property crimes for the SFBU:

- Limited to 3 items (not including known reference samples).

- Touch DNA analysis will only be performed on evidence that would likely contain DNA resulting from the transfer of epithelial cells from the skin to an object due

  to extended contact (i.e. clothing,  cigarette butts, items drank from, etc.).

- "No suspect" DNA analysis which does not meet CODIS eligibility requirements will not be accepted.



Cold cases are cases in which all reasonable leads have been exhausted.  Previously processed evidence (or evidence never previously analyzed) can be reprocessed using the latest techniques and provide new clues.  The SFBU evaluates a case to determine if there is evidence that can be tested and then prioritizes the testing of those items.

Specific requirements of evidence submittal for cold cases for the SFBU:

- Cold cases will be accepted for analysis on a case by case basis  
- Please contact the SFBU for an appointment to evaluate a case prior to submitting evidence

All DNA requests should be submitted with known reference samples from the victim(s), suspect(s) (if applicable), and exclusionary samples as necessary.
