PIERRE, S.D. (AP) – A Maryland man and a Nevada woman are accused of an investment fraud scheme involving an American Indian tribe in South Dakota.

Attorney General Marty Jackley says 59-year-old Greg Long of Hanover, Md., and 54-year-old Alcinda Miller of Las Vegas allegedly misled investors about the legitimacy of a tribal charter to operate a credit union on the Yankton Sioux Reservation.

He says the two collected $370,000 from several investors. Long and Miller each face grand theft and forgery charges.

Long was arrested in Hanover and Miller in North Dakota. Telephone listings for the two could not immediately be found. It was not immediately clear if either had obtained an attorney.
