On March 13, 2013, the FBI updated its list of "Ten Most Wanted Fugitives" by adding the name Edwin Rivera Gracias - seen here, bottom row, 3rd from left.
According to the FBI's website, the list is a publicity program designed to publicize particularly dangerous fugitives who might not otherwise merit nationwide attention, according to the FBI's website.
The program was founded on March 14, 1950, when a reporter asked late FBI Director J. Edgar Hoover for the names and descriptions of the "toughest guys" the Bureau would like to capture. The resulting article generated so much publicity and had so much appeal that Hoover implemented the top ten program.
Since its inception, 497 fugitives have been on the top ten list. Among those listed, the FBI says that 466 have been apprehended or located, including 154 fugitives who were captured or located as a result of citizen cooperation.
The current top ten list is maintained on the FBI website and relies on the assistance of citizens and the media. A reward of up to $100,000 is offered by the FBI for information which leads directly to the arrest of a Top Ten fugitive. Members in the Top Ten list are not ranked.
