The beginning of the "Ten Most Wanted Fugitives" list dates back to 1949.(26)When a reporter for United Press International called the FBI and asked them for the names of the "toughest guys" that the agency wanted to capture, the FBI provided him with a list of ten criminals it believed to be the most dangerous. This list was then published on the front page of the Washington Daily News and received wide public attention. And the help of the American public soon led to several arrests. Over the years, the kinds of criminals on the list have changed. During the 1950s, the "Top Ten" list mostly included escaped prisoners, suspected murderers or people who stole money from banks. During the 1960s, the list included kidnappers, criminals suspected of sabotage(蓄意破坏)and those who stole government property. Today, the list includes people suspected of crimes including terrorism, drug dealing, financial wrongdoing and murder. A suspect must meet two requirements to be on the "Ten Most Wanted Fugitives" list. He or she must be considered a threat to society. And, the FBI must believe that wide publicity about the criminal might help lead to an arrest.(27)A suspect is removed from the list if he or she is captured, found dead or surrenders. Suspects can also be removed from the list if the federal case against them is dismissed or if they are no longer believed to meet the "Top Ten" requirements. Once a suspect is removed, a new suspect is placed on the list.
