Lawrence postal officials have launched an investigation into possible federal violations of postal law related to an anonymous, spurious postcard attempting to link City Commissioner David Schauner to domestic abuse.

Schauner, who is in the middle of a tight re-election battle, has denied all allegations of domestic abuse and denounced the postcard as a political cheap shot. No one has taken responsibility for mailing the card which was received by registered women voters across the city.

Judy Raney, Lawrence postmaster, confirmed today that she has no record of the postcards being appropriately registered with the Lawrence Post Office. Because of the type of stamp that was used on the mailing, Raney said postal regulations required that a report be filed with the post office’s bulk mail department.

Raney said she has turned the matter over to postal investigators to determine if violations were committed.

“The content of the postcard is not our problem right now,” Raney said. “The incorrect use of a pre-sorted stamp is the issue.”

Raney said she was not certain of exact fines or penalties that an individual could face for improperly mailing the postcard.

“What I can tell you is that we’re absolutely taking it seriously,” Raney said.
