Jquery.min.js version 1.9.1 loading twice

In the console i see that jquery.min.js version 1.9.1 is loading twice, i have looked through my template files and do not see where it is loading, which makes me think it is apps loading it both times. Is there any sort of code i can add to my index.liquid that would tell the browser not to load it a second time if it has already been loaded once.
