Puddle on the Living Room Floor?!

 20 Sep 20 - This morning we saw a puddle right next to the couch in the living room right where you come in from the front door.  I started pushing on the wall and found a soft spot just below the window.

It is a little soft and moved when I pressed on it.  We have had some pretty heavy rains for the past 2 days.

You can see the water coming out from between the grey board and the white plaster when I peel them apart.

The water was still dripping from the bottom of the window frame and from the firing strip.

The paper on the back of the drywall was moldy.  Have a small fan on it right now and have sprayed it with bleach to get rid of the smell.  Going to have to remove more of the wall to find where it is leaking from.  It is always an adventure around this house!
