The Evidence Technician Unit of the Criminalistics Services Division of the Oklahoma State Bureau of Investigation is responsible for the reception, storage, documentation, and handling of the physical evidence submitted to an OSBI Laboratory.
Evidence Acceptance Hours:
Evidence will be accepted between 8 AM-4 PM Monday through Friday.
Officers submitting evidence must be at our facility before 4:00 PM to begin submitting evidence. Our Evidence Tech Units will close promptly at 5:00 PM each day. As a result, if an evidence submittal is started before 4:00 PM but not completed by 5:00 PM, the remaining evidence will be returned to the officer, and he/she will be required to return the next business day to complete the evidence submittal.
Therefore, to avoid any inconvenience, officers with large amounts of evidence to submit are encouraged to submit the evidence to the OSBI lab early in the day.
The Southwestern Regional Facility in Lawton, Oklahoma is no longer available for laboratory analysis. This facility continues to provide evidence acceptance.
Effective May 2, 2016, the OSBI facility in Lawton will be open from 7:00 AM to 5:00 PM Monday through Thursday. Our Lawton facility will be closed on Fridays.
