(I know I'm late to the party, but I hope you guys don't mind. Changed his rifle proficiency for bow and arrow skills.)
Trystan Nemico held his knife ready, his bow and arrows strapped silently to his back. The zombie, a walker of a group he'd spotted on the hills, was about to go back to being dead. He smirked, hucking the knife by the blade straight for the spinal cord. It made contact, and the bastard undead dropped like a stone. His shook his head, sighing as he retrieved his knife from the spine. Since the zombie wasn't completely dead, he had to decide what to do with it. Shrugging, he left, but after making sure no more sound could come from the soon to be starved walking corpse. Impressed with himself, he walked on, heading towards a building he'd spotted not that far away. He stopped by the bush where he'd stashed his supplies, which contained 6 more knives of varying sizes, a few days worth of food, and quite a few medical supplies. Being a RN by profession, he knew how to patch up injuries, and since he hunted on his free time, he was quite the shot with his bow. Unfortunately, he didn't know there were other people in the structure. He broke one of the tripwires, and realizing what he'd done, he ducked, rolled and covered in case something bad should happen.
