which the county treasurer or any member of the board of county

commissioners is the owner of any stock or otherwise directly or

indirectly pecuniarily interested. A county treasurer or county

commissioner shall be considered to be interested in such bank if

any member of his immediate family owns any interest in said

depository bank. Any person who violates the provisions of this

section shall, upon conviction, be guilty of a Class D3 felony

offense and shall be punished by imprisonment as provided for in
