IPHONE destroyed

The other day I took the kids to the park. Something I do not do often. After we were there about 20 minutes I asked Hope to go get my cell phone. She said mom it is not here. I told her to look in the back. She then yelled in front of everyone. Mom your cell phone is broke. I said okay no problem. She said no mom it is broke as in stuck in the door broke. I had set it on the back of the suburban and then slammed the door shut on it. The crazy thing is that the otter box was not destroyed just the actual IPHONE screen.
