Sex Offender Gaps
If a comparison of a state's registered sex offender database to the CODIS database reveals a gap, those offenders will likely fall into one of the following categories:
- Offender was convicted before legislation took effect and moved to the registering state
- Offender was transferred pursuant to the interstate compact, and a sample for DNA analysis was not collected
- Offender was covered by state law, but a specimen was not collected
- Offender was not covered by state law
Offender Was Convicted Before Legislation Took Effect
Only retroactive legislation will require this category of offenders to submit a sample for DNA analysis. Most states allow persons to submit a specimen by consent. In the absence of state law, consent is the only vehicle by which this sample will be entered into the database. Coordination with the state crime laboratory is essential in consent submission.
