DNA Database Expungement

Qualifications and Instructions for Removal of an Arrestee DNA Sample

DNA samples are collected from all adults arrested for felonies. The DNA profile will be entered into the DNA database once a person is charged with a felony. Under certain conditions, the person may apply to have their DNA sample removed. 

The removal of a DNA sample from the DNA database is called “expungement”. You will qualify for sample expungement under the following conditions:

1. Samples on file where the charges were dismissed, the case was acquitted, or the conviction for the offense was not a felony.

(There must be a final court order for the above.)

2. Samples collected where no charges are filed or a felony charge was not filed within ninety days of arrest.

Expungement requests must be made in writing. Please complete the DNA Removal Request Form, print it, and sign it.  Forms may also be requested in person at all CBI offices, by telephone or by mail.

One form must be completed and signed for each arrest where an expungement is requested.

Forms can be mailed or hand-delivered to the following address:

Colorado Bureau of Investigation
DNA Database Section
6000 W. 54th Ave. 
Arvada, CO 80002

The CBI has ninety days to comply with the request. You will be notified of the results of your request by first class mail.

For questions, please call our automated telephone system at (303) 239-4668 and leave a message. Your call will be returned in a timely manner.
