From what I read so far this is what I understood.
1. You were in the tree, theres no possible way you could have seen anything through the door.
2. You suspected that it was Milk due to the sound of the gun, maybe another person could have jumped out of the window.
3. You dug a hole for yourself since so far you literally countered yourself on every statement.

In my opinion this should be denied due to lack of evidence and shady story.
