Editing core demographic data (i.e. name, race, gender) or deleting incorrect secondary demographic information (i.e. SSN, DOB, State ID) can only be done by a state admin from the supervising state of the offender.
As you can see below, you need to go to the offender management tab and enter the offender number after selecting 'Edit Offender Demographics'.
The next screenshot shows the page where you can change the offender's core demographic data and then click the 'Submit' button. All assigned users on the case will receive an email notification regarding the change.
The other tabs allow you to delete incorrect data regarding social security numbers, dates of birth, aliases, state ids, and photos.
