the zodiac killer but it’s just a guy threatening murder because he’s sick of all the articles/stories/puzzles he submits to the paper being rejected and this is the only way to get his shitty submissions published
or a guy who uses that to obscure the real motive for a murder/string of murders because he’s trying to protect the person who’d otherwise be accused of them and the real answer is even more insane
stiles is the zodiac killer au in which he stops people from looking at derek like he’s a murderer (how the turntables) by using the zodiac code-and-hints-and-threats thing to make it seem like the zodiac also committed a murder derek has an alibi for
he’s able to provide/confirm holdback info on the crimes because he snuck into the station and read the official files
as a bonus, his puzzles and codes all lead to psychotic hunters with too much visible blood on their hands for anyone to question if they were really involved
derek’s half impressed, and half… well we’ll leave it at that
