A federal appeals court has upheld the 8-year prison sentence given to the longtime girlfriend of reputed gangster James "Whitey" Bulger for helping him during his 16 years as a fugitive.

The 1st U.S. Circuit Court of Appeals ruled Friday that it found no reason to disturb the sentence Catherine Greig received after she pleaded guilty to conspiracy to harbor a fugitive and other charges.

Bulger, the former leader of the Winter Hill Gang, fled Boston in late 1994 and remained a fugitive until he and Greig were captured together in Santa Monica, Calif., in 2011.

Prosecutors said Greig helped Bulger in multiple ways while he was hiding from law enforcement.

The now 83-year-old Bulger is scheduled to go on trial in June in an indictment charging him with participating in 19 murders.
