Three members of the Lucchese crime family in New Jersey have been sentenced to state prison after pleading guilty to running an international gambling enterprise.

Sixty-nine-year-old Ralph Perna, of East Hanover, was sentenced to eight years in prison and his two sons, John and Joseph, were sentenced to 10 years.

Authorities say Ralph Perna had led the mob family's New Jersey operations.

The father and sons were among six mob Lucchese crime family members who pleaded guilty for their role in the ring in October.

The defendants were arrested in 2007 after investigators targeted an international criminal gambling enterprise that they say handled billions of dollars in wagers, primarily on sporting events.

Charges are still pending against 20 of the 34 people originally indicted in the case.
