We spoke to a Lubbock mom who said she's frightened by the though of her girls walking by the house of a registered sex offender.
"I think its a great idea it make me feel a whole lot safer."
Now she has less reason to worry, thanks to a program from the county's supervision and correction's department that gathers up registered sex offenders on Halloween night and keeps them locked in one place.
"The last we had checked there are around 500 registered sex offenders in Lubbock," said assistant director, Farrell Martin.
He said Halloween night about 70 sex offenders on probation will be taken to a secret location.
Those offenders at home who are on parole will be monitored by officers making sure they do not have a light on and do not answer the door to trick-or-treaters.
"It does give you a little peace of mind that the ones we're aware of we have control over we bring them in and they are being supervised," said Martin.
But he does warn parents there will be offenders at home on Halloween night.
"I'd urge the parents to just be cautious going out and have fun trick-or-treating, but just be aware that just because we are having this program doesn't mean we have all of them," said Martin," we don't we have the ones that that we have control over.".
