Recently I had some folders on my Desktop that I had moved into the Trash.  Some of these folders contained files with the owner root.  Once these were in the Trash, I was not able to completely empty the Trash due to the Permission Settings of the files.  I found several places that showed that the Trash location was

/home/USERNAME/.Trash

This was not the case for me.  Instead mine was located at

/home/USERNAME/.local/share/Trash

Once I found the location, I was able to use the following command to completely remove all contents from the Trash

cd home/USERNAME/.local/share/Trash

sudo rm -rf *

Note: Be extremely careful with the above command!!  If not in the correct directory, the above command would remove all files from /.
