A longtime fugitive and Boston Mafia associate who spent years on the lam as an Idaho rancher was sentenced Thursday for unlawful possession of firearms

U.S. District Judge Edward Lodge sentenced Enrico M. Ponzo, aka Jay Shaw, to serve 46 months in prison.

Half of that prison sentence will be completed after he finishes a separate 28 year prison sentence in Boston. In 2013, a jury found him guilty of two counts of attempted murder and numerous other charges.

As part of a plea agreement, officials say Ponzo admitted that he knowingly possessed 33 firearms in February 2011 after having been convicted of felony assault and battery.

The FBI and U.S. Marshals arrested Ponzo in Marsing, Idaho, in February 2011, 16 years after he fled Boston.
