BOSTON -- The FBI released audio recordings Wednesday of fugitive mobster James “Whitey” Bulger in hopes that he will be recognized by someone who comes in contact with him.

The audio recordings are from FBI wiretaps and being released because the bureau “believes the international exposure of the recordings will be beneficial to the fugitive investigation,” the agency said in a statement.

Although the recordings were made before Bulger was indicted and became a fugitive, the Bulger Fugitive Task Force said “the unique sound of Bulger’s voice” might be recognizable.

Bulger is charged in 19 murders. He also was an FBI informant. Authorities said he fled in 1995 after his FBI handler tipped him off that he was about to be indicted on racketeering charges.

That former agent, John Connolly Junior, is serving a 10-year prison sentence.

Bulger apparently planned for life on the run by leaving cash in safe deposit boxes around the world.

The FBI said Bulger's last confirmed sighting was in London in September 2002. A reward of up to $1 million is being offered for any information leading directly to his arrest.
