Three people linked to a gang prominent in Idaho prisons have been sentenced to 2 1/2 to more than 4 years in prison.

Rory Vincent Palma, 38; Joshua Michael Trent, 32, of Boise; and Christina Shantell Massie, 35, of Boise; were among 23 people charged in a federal investigation into the Aryan Knights, who are said to be responsible for the distribution of methamphetamine in Idaho.

Palma, of Tempe, Ariz., was sentenced Monday to 41 months in prison and three years of probation for unlawful possession of a firearm. Palma's three previous felony convictions include two for unlawful possession of a firearm. He sold a shotgun to a confidential informant, leading to a grand jury indictment.

Trent was sentenced to 51 months in prison and three years of probation for possessing an unregistered firearm, and Massie was sentenced to 30 months in prison and three years of probation for unlawful possession of a firearm. Massie has two previous drug felonies that prohibit her from lawfully possessing weapons.

Of the 23 people charged, 16 have pleaded guilty, two have signed plea agreements but not yet entered guilty pleas and five are set for trial, according to the U.S. Attorney's Office.
