A center spokeswoman said that number was just a small fraction of the 10,628 reports of missing U.S. children it had received during the year. The bulk of the cases weren't posted for a variety of reasons, including that they had been found or information was still being assembled.
A number of the U.S. cases made national news, including the search for California teenager Sierra LaMar.
Sierra disappeared on the morning of March 16 as she made her way to school in Morgan Hill; she was 15 at the time. Antolin Garcia Torres, 21, of Morgan Hill, was charged with kidnapping and murder in the case in May, but Sierra's remains have yet to be found. In October, Sierra's parents celebrated the teenager's 16th birthday.
"We're not in a real celebratory mood," said Sierra's mother, Marlene LaMar, told The Fremont Argus. "That's probably going to be the toughest day in terms of missing her."

Mark Redwine, who Elaine Redwine accused of being involved in their son's disappearance, hired a criminal lawyer in early December.
