 Among the broken sculptures left by looters, Stuart found textual references to a place name and to historical figures that were featured on Site Q artifacts, leading him to believe that La Corona was Site Q.In 2005 Marcello A. Canuto, then a Yale professor, found a panel in situ at La Corona that mentioned two Site Q rulers.The panel had been quarried from the same rock as the Site Q artifacts, providing convincing evidence that La Corona was indeed Site Q.
