Click here to listen to Newsradio 620 WTMJ's Tim Lethlean report on how Milwaukee Co. Sheriff's deputies kept an eye on sex offenders who could have enticed children with candy during trick-or-treat.

Plenty of Milwaukee County Sheriff's deputies were going door-to-door on Sunday, but they weren't looking for candy.

"Nobody has been knocking on your door besides us today?" asked a parole officer to a convicted sex offender.

That offender responded, "no, no."

Those deputies, along with parole officers, were checking up on registered sex offenders during trick-or-treat hours. 

There are strict regulations that prohibit sex offenders from participating in trick-or-treat in any way. 

"They shouldn't have any lights on, they shouldn't have any candy, they shouldn't be promoting trick or treating at their residence because that's being non-compliant," said Sheriff's Detective Paul Thompson.

In fact, those offenders aren't even allowed to answer their door during the trick-or-treat hours set by the community. 

Deputies say most sex offenders they checked in on were following the rules, only a few were taken into custody for disobeying.
