It turns out that Vieria was right- TMZ did end up posting this news. And according to the site, the actor, who died at 59, will have two funerals- one for his family and another for his fans.

While Weatherwax was known for playing Pugsley in the TV version of the "creepy and spooky" family, he also voiced the character in Halloween With the New Addams Family, which came out in the late 1970s. After this, it seemed like he put the acting days behind him and moved on to different kinds of work, including grip and set building behind the scenes.

Even though he was no longer part of the Addams clan or any other kind of acting clan, he still managed to make appearances at fan conventions.
