Child abduction remains a problem in America although technological advances are helping police to recover children more quickly, experts say. According to the National Center for Missing and Exploited Children, 460,699 entries for missing children were logged into the FBI’s National Crime Information Center in 2015. The number represents reports of all missing children in the U.S. and was slightly lower than the 2014 data. In June 2016, the Office of Justice Programs’ Office of Juvenile Justice and Delinquency Prevention (OJJDP) reported in its monthly bulletin that the number of children kidnapped by strangers, or slight acquaintances, has remained constant, but that the number killed has declined. The research reviewed and compared data from 1997 and 2011.
