MARTINSBURG, W.Va. -- The government says a grand jury sitting in Martinsburg has handed up indictments against five men on conspiracy charges alleging they were involved in a marijuana trafficking operation involving six states.

The charges announced Tuesday claim the defendants trafficked the drug in Arizona, Florida, Kansas, Missouri, Ohio and West Virginia. Prosecutors said the men dealt an unspecified amount of marijuana.

Named in the indictment were 29-year-old Nicholas Avery Arthur of Key Largo, Fla., 27-year-old Dylan Ross Banker of Shepherdstown, 27-year-old Jonathan Thomas Carnill of Martinsburg, 39-year-old Gregory Scot Burlett of Ranson and 34-year-old Jonah Blackwell Tremba of Charles Town.

The government said the defendants face punishments ranging from five to 40 years in prison and fines of up to $1 million.

It was not clear if the five have attorneys.
