KANSAS CITY, Mo. -- An electronic billboard in Kansas City calls for the resignation of the highest-ranking U.S. church official to be convicted of a crime related to the child sexual abuse scandal.

The Kansas City Star reports that the sign, located along Interstate 35, directs passers-by to an online petition that urges Bishop Robert Finn to step down. So far, more than 100,000 people have added their names.

Large letters read: "For the good of the people Bishop Finn must RESIGN!"

Finn was convicted last month of one misdemeanor for failing to report child-abuse suspicions.

The charges stem from a case in which church officials knew about child-porn photos on a priest's computer but didn't turn him in until six months later.
