Eric Justin Toth (alias/a.
k.a. "David Bussone") (born February 13, 1982) is an American former fugitive wanted for allegedly possessing and producing child pornography.
 He was caught in Esteli, Nicaragua on April 10, 2013 and extradited on April 22, 2013 to the United States to face trial.
 On April 10, 2012, Toth replaced Osama bin Laden on the FBI Ten Most Wanted list as the 495th fugitive to be placed on that list by the FBI.
 One alleged reason he was chosen for the list is that his distinctive appearance—he is tall and thin, with a mole under his left eye—would make it hard for him to hide if his case became well publicized.
In the 1950s, the United States FBI began to maintain a public list of the people it regarded as the Ten Most Wanted Fugitives.
 Following is a brief review of FBI people and events that place the 1950s decade in context, and then an historical list of individual fugitives whose names first appeared on the 10 Most Wanted list during the decade of the 1950s, under FBI Director J. Edgar Hoover.
The FBI Seeking Terror Information list is the third major "wanted" list to have been created by the United States Department of Justice's Federal Bureau of Investigation to be used as a primary tool for publicly identifying and tracking down suspected terrorists operating against United States nationals at home and abroad.
 The first preceding list for this purpose was the FBI Ten Most Wanted Fugitives list.
 In 2001, after the September 11 attacks, that list was supplanted by the FBI Most Wanted Terrorists list, for the purpose of listing fugitives who are specifically wanted for acts of terrorism.
This incomplete list of former FBI Ten Most Wanted Fugitives are convicted felons that have been on the list of the FBI Ten Most Wanted Fugitives.

In the 1960s, for a second decade, the United States FBI continued to maintain a public list of the people it regarded as the Ten Most Wanted Fugitives.
 Following is a brief review of FBI people and events that place the 1960s decade in context, and then an historical list of individual suspects whose names first appeared on the 10 Most Wanted list during the decade of the 1960s, under FBI Director J. Edgar Hoover.
Yaser Abdel Said (born January 27, 1957) is a fugitive on the FBI Ten Most Wanted List.
 An Egyptian resident of the United States, he is wanted for the murder of his two teenage daughters in Irving, Texas.
The FBI Ten Most Wanted Fugitives is a most wanted list maintained by the United States Federal Bureau of Investigation (FBI).
 The list arose from a conversation held in late 1949 between J. Edgar Hoover, Director of the FBI, and William Kinsey Hutchinson, International News Service (the predecessor of the United Press International) editor-in-chief, who were discussing ways to promote capture of the FBI's "toughest guys".
 This discussion turned into a published article, which received so much positive publicity that on March 14, 1950, the FBI officially announced the list to increase law enforcement's ability to capture dangerous fugitives.
