great photos, seems odd to me that Warrick slumps forward when getting shot from his right, doesn't seem to be much bleeding either, no carotid artery damage apparently
I'm watching the end over and over, he's not wearing any gloves so he'll have gunshot residue, possible palm/knuckle prints, no silencer, wipes the gun off with his hankie and stuffs the hankie back into his pocket, doesn't seem to be in any hurry to get out of there after firing twice.
I think it was because Warrick was investigating Gedda, had hired that private detective and such, getting in too deep and was about to find out about the undersheriff and his corruption. Had Pritchard Kill Gedda and attempted to frame Warrick for it, but when that went awry the undersheriff...
The one shot went thru the neck, missed the main artery, I'm guessing the 2nd shot was also not a killing shot, Nick heard the shots and runs outside immediately. I think Warrick will live
