BOSTON, Massachusetts — The girlfriend of a feared Boston gangster captured after 16 years on the run from multiple murder charges was herself indicted Thursday on a charge of conspiracy to shelter the fugitive.

Catherine Greig, 60, was indicted by a federal grand jury and faces up to five years in prison and a $250,000 fine if convicted.

She is alleged to have conspired with James "Whitey" Bulger, accused in 19 murders, to conceal him during his time on the run.

"It is alleged that Greig conspired to take steps to prevent Bulger?s discovery and arrest, after knowledge of the fact that a warrant had been issued," the US attorney?s office said.

On July 6, Bulger, 81, pleaded not guilty to the murder charges. He was captured in June after escaping to California where he lived under an assumed name until his shock capture.

In addition to accusations that Bulger murdered mob rivals, potential witnesses and others who either threatened him, prosecutors accuse him of a crime spree spanning into the 1990s that included extortion, money laundering and, at one point, running guns to Northern Ireland's IRA militants.
