The government’s decision to drop a bribery case involving a former regulator and utility owner leaves the question of what will come of its parent investigation.

On Tuesday, prosecutors filed a motion to dismiss all charges against former Arizona Corporation Commissioner Gary Pierce, his wife, Sherry Pierce, lobbyist Jim Norton and utility owner George Johnson.

Gary Pierce and his fellow co-defendants aren’t off the hook yet, despite the government’s failed attempt to convince a jury they were part of a scheme to bribe the former utility regulator.

A majority of the jurors in the “Ghost Lobby” trial voted for acquittal for all four defendants, foreperson Taryn Jeffries said in an exclusive interview with the Arizona Capitol Times.
