WELLESLEY, Mass. -- A little girl chasing her dog led police in Wellesley to launch a major search effort Sunday afternoon.

Police said Annie Leonard, 2, took off from her yard to go after her pet without anyone noticing. When the girl could not be found, police were called and the search began.

Nearly two hours later and with the help of a regional search team and neighbors, the girl was found across the street with her dog, Booker.
