THE BRONX - The kidnapping and death of a Brooklyn boy has left many parents on edge, and now experts are offering advice on how to keep children safe.

Leiby Kletzky, 8, was abducted while walking home from camp. Police and prosecutors say 35-year-old Levi Aron confessed to luring Kletzky to his home on Monday, and then smothering and dismembering the child after learning that a search was under way for the 8-year-old.

Billy Jones Mulraine, assistant executive director of clinical programs at Kingsbridge Heights Community Center, says it is important to educate children, but to not instill fear in them. Mulraine, who is also a child therapist, says parents should help their kids establish boundaries and make sure they know they don't have to always be polite, even with people they know.

Mulraine admits that "stranger danger" education is very difficult. She says parents can't just tell kids not to talk to strangers because they may need a stranger's help one day. In fact, according to Mulraine, statistics show that nine times out of 10, perpetrators prey on kids they know.

Experts also warn parents to not shield their kids from stories like the Kletzky case, which could be used as a teachable moment.
