TECUMSEH, Mich. (AP) — A southeast Michigan couple faces jail time over two late books that they failed to return to their local public library.

Cathy and Melvin Duren of Tecumseh each were charged Thursday in Lenawee County with a misdemeanor charge of failure to return rental property.

WXYZ-TV reports that the couple thinks it’s unfair that they never would’ve been charged if they each paid a $105 “diversion fee” to the Lenawee County Economic Crimes Unit, plus fees owed to the Tecumseh Public Library.

The Durens received a letter about the overdue books in December. They were able to find and return one of the books in January.

Cathy Duren sent a $55 money order to the prosecutor’s office to cover the late fees and replacement cost for the lost book.

The couple is due in court within 10 days.
