"Nearly 1,800 Massachusetts sex offenders did not have a current address on file with the state’s registry, and close to 1,000 of those convicted criminals had not been classified by their likelihood to reoffend, according to an audit released Tuesday by state Auditor Suzanne M. Bump.

The state Sex Offender Registry Board neglected to verify addresses with agencies in the state’s executive branch — such as the departments of Revenue and Transitional Assistance — despite having agreements with those agencies to use their data to confirm addresses, and being required by law to do so, the audit found, according to a statement from Bump’s office.

The audit covered the period from July 1, 2015, to June 30, 2016."
