Walter Lee Williams, a former university professor, is wanted for the alleged sexual exploitation of children and traveling abroad for the purpose of engaging in illicit sexual acts with children.

A list that has included notorious names such as James Earl Ray, Ted Bundy, Whitey Bulger and Osama bin Laden reached a milestone Monday.

With the addition of an alleged child rapist and an alleged killer, The FBI's "Ten Most Wanted Fugitives" list has now included 500 fugitives.

The latest additions fill vacancies created this spring with the capture and surrender of two fugitives.

Jose Manuel Garcia Guevara allegedly murdered a 26-year-old woman in the presence of her four-year-old stepson in Lake Charles, La., in 2008.

“These individuals are a dangerous menace to society,” said Ron Hosko of the FBI's Criminal Investigative Division in a news release. “That’s what got criminals on the Top 10 list 63 years ago, and that’s why we put them on the list today.”

Jose Manuel Garcia Guevara, the 499th fugitive on the Top 10 list, allegedly raped and stabbed a 26-year-old woman in Louisiana in front of her 4-year-old stepson, according to an FBI news release. He is wanted for fleeing the crime to avoid being prosecuted. Authorities think he may have fled to Mexico.

Walter Lee Williams, the 500th person on the list, allegedly engaged in sexual acts with children both domestically and abroad. He is a former university professor with ties to Southeast Asia.

Launched in 1950, the FBI's most-wanted program has a 94 percent success rate. Only eight of the 500 fugitives on the list have been women, according to the FBI.

One man, Billy Austin Bryant, spent only two hours on the list before he was caught in 1969.

Others have spent years on the list avoiding capture. Bulger, the reputed Boston mob boss currently on trial, was on the list for 12 years before his apprehension in 2011.

Robert William Fisher, wanted for allegedly killing his wife and two young children and then blowing up the house in Arizona, has been on the FBI's most-wanted list since 2002.

Former university professor Walter Lee Williams, the 500th person to be named on the FBI's iconic Ten Most Wanted Fugitives list, is sought for allegedly engaging in sexual acts with children both domestically and abroad.
