America’s most wanted man is 81 this Labor Day weekend, but the FBI is not giving up the hunt for Whitey Bulger, wanted for 19 murders from his time as head of the Boston Irish mafia. The Oscar winning movie ‘The Departed’ was based on Bulger.

FBI Supervisory Special Agent Richard Teahan says “We haven’t gone away. The game plan hasn’t changed.”

“Our mindset is that no matter what his age is we will keep looking for him as vigorously as we did when he disappeared back in 1995 until we get some kind of credible information that he’s deceased,” Teahan, captain of the FBI’s Bulger Task Force, told the Boston Herald.

Bulger, the brother of former state Senate President William “Billy” Bulger, was last seen in London in 2002. He is the former boss of the Winter Hill Irish gang in South Boston.

He’s believed to still be traveling with girlfriend Catherine Greig. Greig, 59, a dental hygienist, also has a  warrant for her arrest since 1997, when she was charged with harboring a federal fugitive.

“As best as we can tell, (Bulger’s) alive and well with Catherine Greig and they are living a quiet existence somewhere under the radar, which makes it harder to locate them,” Teahan said.

“It is a very challenging case because of not only who he is - elusive, bright, smart - but because he’s also traveling with a woman,” Teahan said. “They just don’t look suspicious.”
