New York state is not doing enough to monitor dangerous sex offenders, according to a new audit from state Comptroller Thomas DiNapoli.

The report finds that parole officers are failing to adequately monitor sex offenders, including those under the Strict and Intensive Supervision and Treatment program, or SIST.

By law, parole officers are required to conduct two home visits and two curfew checks per month. The state audit says that nearly a quarter of 92 cases examined showed the minimum monthly face-to-face contacts had not happened.

The audit also found that two-thirds of the law enforcement agencies reviewed failed to update photos of paroled sex offenders every 90 days, as required by law.

Corrections officials say they will use the audit to improve supervision.
