Finding the Sidebar

I’m using the theme – peaceful rush 10 and I’m trying to find where code where the sidebar is being included but can’t find it. In most themes, I can find a get_sidebar() call in the index.php file for example.

In this index.php I see the get_header() and get_footer() but no get_sidebar().

Where is it getting called from? I would like the sidebar removed on one of my custom pages.

Thanks!
