KENOSHA, Wis.—Someone in Texas apparently had a guilty conscience, paying up on a parking ticket handed out 21 years before.

The Kenosha Police Department says officers found a $6 payment for the ticket, issued Jan. 20, 1987, in a drop box.

A notice on the ticket indicated that failure to pay within 120 hours would result in doubling of the $3 forfeiture.

It was signed by a man who listed a Dallas address.
