Sawyer Huxley the Signment.

Sawyer, or Tiana as his parents named him, started off with a darker mind set then most. Sawyer wished he could say he was a anti-hero of sorts but he wasn't, he killed just to kill, and to feel the adrenaline afterwards. Every spike of his pulse when he hears those sirens moving towards his hunting spot, every rush in his blood when he heard someone scream from his hands. He began this all when he was younger, No he didn't have bad parent, no abuse, no neglect. He just felt it one day and started to act on it. Of course when he was young he was told rules to follow, don't do this, don't do that. He listened to most, like any normal insane person would, starting on animals. He would never harm a cat or dog or any popular species, but the less popular ones he did. He hurt and tortured birds and squirrels, gutting and such. Eventually one day when his mother found a few photos of animals torn up in his room, he got a talk he wasn't a fan of, an asylum? He wasn't insane. He was just being himself, which is why he chose to remove them from his life. That night while he was told to pack he instead took a knife and removed his parents and sister from his life forever. He wasn't sure what to do after that so he just ran. He ran away and found a new life, as he grew he changed, got smarter with his tricks and figured out how to hide evidence. Even teasing the police here and there, at some point after deciding he didn't want to be the sex he was he changed that too. He stole the medication needed, threatened a doctor into giving him the proper top surgery and then of course tricking that doctor by killing them even after promising to let them live, he wasn't a kind man and he never would be. Mind your business and he'll most likely leave you be, he likes to pick targets specifically. Choosing someone over something small like the way someone dressed was too boring, or their dog barked too loud at him when he walked past. He stalks the person for a few days before making his move and killing them in the most gore way he could and taking a photo before leaving, normally taking the photos right to his darkroom in his house. He was a simple man at most, so he kept his ' disguise ' simple to, during killing he just walked around in a handmade mask, black baggy army pants, combat boots and of course he wore a hooded top, which due to style preference was leather and had a few tightly stuck on pins so they didn't rattle.
Out of killing he was simple as well, a pale man with semi short messy hair and a greasy look to him, thought he was much more clean then he looked of course, he wore simple clothes such as a jacket and sweatpants as he didn't do much all day besides work, which was at a cheap grocery store due to his lack of school experience.
