Four inmates face new charges from their cells in [FCI] El Reno, authorities said.

Investigators have accused the men of copyrighting their names and demanding millions of dollars from El Reno prison leaders for using their names without permission.

Court papers showed the inmates filed liens against the warden's property and then actually hired somebody to seize his vehicles, to change the locks on his house and to freeze his bank accounts.

The inmates were identified as Russell Dean Landers, Clayton Heath Albers, Carl Ervin Batts and Barry Dean Bischof.
