How to remove rear bumper

I used the search and found nothing, is there a how-to remove the rear bumper, the trunk is leaking and we have found the leak, and we can not get to it without removing the rear bumper, does anyone have a how to for this? Thanks!

There are two screws under the bottom of the bumper where it connects to the frame, two in each wheel well where it connects to the quater pannels, and about five accrost the top where the trunk closes on the rear bumper at. Good luck
