Well, drew part of this from a picture, which can be found here and made part of it up myself. I enjoyed doing this. Adding details and stuff. It's fun. Plus, since I didn't recognize the original scene, I made my own story to go with it.
What happened here? He was obviously hit on the head with the blunt object on the table, but what else? Why is he clutching his chest? If it would've been a heart attack of some kind, and he would've been hit post-mortum, there wouldn't be any blood, or not as much anyway. Was he having pain first and hit later? Was he dead immediately after the hit? What's the paper slip Gibbs is holding? Who is the guy standing in the front? So much fun! Lol, I actually pay attention when watching the series.
