A reputed New England mobster who was caught in Idaho after evading authorities for more than a decade has been indicted on additional federal charges.

Enrico Ponzo disappeared in 1994 after allegedly attempting to kill a Massachusetts mob boss. He was captured last year while living under an alias in an Idaho town.

A federal grand jury in Boise indicted him Tuesday on firearm and identity theft charges related to his time in Idaho. Ponzo is accused of owning more than 30 firearms and stealing the identities of several people.

Authorities say Ponzo is already in custody in Massachusetts on charges of racketeering, conspiracy to murder and attempted murder.

He now faces additional counts of unlawful possession of a firearm and aggravated identity theft, among other charges.
