WICHITA, Kan. (AP) — Federal prosecutors have charged a former bank president and two of his customers in a conspiracy to launder drug money in Kansas for Mexican cartels. Two other former bank employees were also charged with failing to report the suspicious financial transactions.

The U.S. attorney’s office says the 37-count indictment unsealed Tuesday in Kansas is part of a larger investigation with indictments across the country. That probe has resulted in 20 indictments against defendants in Indiana, Texas, Massachusetts, Georgia, Oklahoma, Colorado and Mexico.

Prosecutors say George Enns and his wife, Agatha, of Meade, Kansas, deposited millions in drug proceeds into their account at the Plains State Bank in Kansas while former bank president James Kirk Friend of Plains failed to report the suspicious activity.
