OKLAHOMA CITY -- Thousands of men and women have been convicted of everything from indecent exposure to sexual exploitation, child porn to rape.
Many have served their time and are quietly living among us.
"There's more sex offenders in Oklahoma City than police officers, and we have over 1,100 police officers, " MSgt. Gary Knight, with the Oklahoma City Police Department, said.
NewsChannel 4 spent several weeks crunching the numbers and exposing Oklahoma City schools with the most convicted sex offenders living nearby.
"They are living there legally. There is nothing illegal about the places where they are living. It's not against the law to be a registered sex offender. But it's certainly something people can keep tabs on," Knight said.
Sex offenders are required to live at least 2,000 feet away from a school. Most comply, but that doesn't stop them from living within walking distance.
"I'm not sure if 2,000 feet is enough protection for our children," Bob Horton said.
Cesar Chavez Elementary School has 29 sex offenders living within a one mile radius.
"Totally surprised to know that there are 29 around the school. There's a lot of kids who walk, and that's crazy. By themselves, no adults, no nothing. Crazy that 29 live around here," said Stephanie Rogers.
Webster Middle School has the third highest population of sex offenders near the campus with 41.
"I never knew there were that many and I lived right next to the elementary. It's pretty hard to believe," said Kerk Roberts.
Hayes Elementary School registered 44 offenders in the vicinity.
"That is absolutely scary. I thought there were laws to protect us from those types of predators," Horton said.
When we searched Bodine Elementary, the results were staggering.
"We are sorry but your search by radius returns too many offenders, please reduce your search radius distance," Ashley Vester said. "I bet if the parents knew how many were around they would have a fit. That's crazy, very surprised."
Police caution that just because a school has more sex offenders nearby doesn't necessarily mean those students are more at risk.
There are those on the list who did not commit violent offenses.
Instead, officials say it's important to talk with your children about "stranger danger."
"You don't want a child walking home alone, a very young child, to be someone's cautionary tale. It's always good for children to walk home in numbers," Knight said.
Oklahoma Centennial High in rural northeast Oklahoma City is the only school in the entire district with no sex offenders within one mile.
