How to request assistance


The DFI Unit is currently exceeding our maximum case capacity. As a result, we will not be accepting any new case submissions or requests from agencies outside of the District Attorney’s Office at this time. Existing forensic requests are being triaged and prioritized on a case by case basis. We are taking these steps in an effort to reduce our backlog and to provide more timely examination results for case submissions. 


To request assistance from the Digital Forensics Investigations Unit, please make sure you have a copy of the legal authority which authorizes the examination of the device(s) you are submitting. 

No evidence will be accepted without proper legal authority at the time of submission.

When you arrive, you will be asked to fill out a Submission Request Form. This form can be filled out ahead of time by visiting our Documents and Forms page here. Please be as detailed as possible so that we can better assist you during the examination. If your case needs to be expedited, please let us know at the time of submission.

If your evidence will require additional testing such as DNA or fingerprint processing, please have this testing done prior to submitting it to our unit. 

If your evidence contains blood or other biohazard material, please have your evidence clearly marked and let us know at the time of submission. 

During the submission process, you will be provided a DFI Control number. Please keep this for your reference, as this is the best way to look up the status of your case.

Case intake hours are from 8a – 4p. If there are special circumstances in which assistance is needed outside of these hours, please contact us ahead of time to discuss.

If you have any questions please feel free to contact us at 713-274-5920.
