The blood splatter on the glass from Eugene shooting Teddy changes between shots.
At 27:35 the character referred to as "3 to 5, 7 to 9" appears at the first wake. At 30:49 at the second wake, which is on the same day as the first wake, the same character appears with a different hairstyle.
At 46:47 just after the suicide is ended the body is shown hanging loosely. If the act was committed by rope around the neck then the clothing would hang loosely. The shirt clearly shows that there was a harness underneath creating tension lines and the neck of the shirt is pulled back rather than hanging down frontally.
