Since December 4th 2016 when a gunman named Edgar Welsh stormed the Pizzeria looking for "evidence" and was arrested. The folks responsible for pushing the Pizzagate theory online backed away after that, and apologized for their involvement.
That doesn’t debunk anything at all, of course. It could have been an actor - and lo and behold that individual indeed has an acting background. A proper investigation is yet to be done in this matter.
I doubt this guy Edgar Welsh was qualified to look for “evidence”. Did he look for signs of recent construction work, for example?
