A concern for parents across Westchester and Hudson Valley this Halloween was the danger of their children coming in contact with sex offenders.

There were two programs aimed at keeping sex offenders from coming in contact with youngsters. On the state level, paroled sex offenders have a curfew that begins at 3 p.m. and runs until 6 a.m. Wednesday. They could not participate in the holiday, including opening their doors to trick-or-treaters. Meantime, Westchester County held a mandatory educational program for sex offenders on probation. That special educational program ran from 6 to 9:45 p.m. at the Westchester County Courthouse. Out of the 166 sexual predators required to be there, all but seven showed up. Police and probation officers are now searching for those seven missing offenders. Police say those who did not comply with this requirement will likely get a violation and will be brought before a judge.
