When Shannon Hyland-Tassava heard about Leiby Kletzky's murder Wednesday morning, she posted her reaction on Facebook.
"This is why it will never bother me to err on the more protective side with my kids if given the option," the Northfield psychologist, writer and mother of two wrote. "I don't care if it's statistically unlikely to happen; IT CAN HAPPEN. Horrifying."
Similar emotions echoed nationwide this week after news broke about the New York City 8-year-old who was murdered and dismembered after getting lost walking home alone from day camp. It's a case that embodies some of parents' worst terrors.
"Immediately I thought, I don't care who calls me overprotective; I'm going to walk my children to and from everything," Hyland-Tassava said in an interview. "Because I can't even bear hearing about things like this when they do happen."
Cases like Leiby's are extremely rare. A study by the U.S. Department of Justice counted 115 children abducted by strangers in 1999. Of those, less than half were killed or never found. Those numbers don't change much from year to year, said Nancy McBride, national safety director at the National Center for Missing and Exploited Children.
Those statistics should be reassuring, but some experts say it's the rarity of such stories -- along with the media attention they generate -- that makes them the stuff of parental nightmares.
"They stick out, they play and replay in parents' minds," said Hara Estroff Marano, author of "A Nation of Wimps: The High Cost of Invasive Parenting."
Despite major progress in children's health and safety, today's parents worry more than ever about protecting their offspring from harm, according to Peter Stearns, author of "Anxious Parents: A History of Modern Childrearing in America." In the past, "there was a greater sense that childhood carried some risks and there was not much to be done about it," he said. Now, "we don't like the idea of any risk."
