Hi mate, sorry for your losses. Please grieve as soon as possible. let those tears flow, curse and berate the world as soon as you can. It clears a lot of crap out of the system and allows you to think differently, not negatively, just differently, about things. I have never lost colleagues in such violent circumstance, but have lost four friends in the last two years. Their deaths were just as sudden and as shocking as the place you describe here. I hope you find closure soon. Peace
