Theft?

Following upon the presumed theft of  the bronze Edwin Denby plaque from the Brodhead Armory, scrappers might be at it again.  Today I noticed that the Dedication Plaque to the "Gateway to Freedom" sculpture at Hart Plaza is missing.  The sculpture is a memorial to the Underground Railroad and has a companion piece entitled "Tower of Freedom" which is located in Windsor.

Maybe, the plaque is being repaired or replaced and was not scrapped.  However, things being what they are right now, I am not all that hopeful.
