Washington State Patrol Sgt. Ted DeHart says that a detective stopped by KMPS, the radio station where the sign was dropped off, and recovered it.
"We've retrieved the document. It will be back up today," said DeHart.
The Patrol is continuing the search for the thief, he said.
"It is a crime. It is theft," said DeHart. "Someone took something that did not belong to them."
Troopers were strolling the capitol halls near the empty sign easel this morning, and DeHart said that capitol cameras have now been pointed toward the sign and other displays nearby.
