The most
insane theory has been saved for last. A Reddit user who goes by the handle “simplyravishing”
posted that “The Yellow King,” who’s presumably at the heart of the ritualistic killings in
True Detective, is none other than “the owner of the Vietnamese restaurant from Episode 3.” His/her evidence for this theory is that Rust and Marty “somehow not only found, but ate at a Vietnamese restaurant in the backwoods of Louisiana,” and that most of the people linked to the cult have been “white guys with white power ideals” like LeDoux and Lange, who would probably refer to a Vietnamese person as “yellow.” Furthermore, there’s the scene where Rust describes LeDoux’s “little shop of horrors as being reminiscent of the way his father described Vietnam,” so we can assume that some nasty stuff went down there. I’ll let simplyravishing take it from here:
The King in Yellow is a Vietnamese refugee who made his way to the United States after the war in an effort to track down Mr. Cohle and any of his living family members to repay him for the atrocities he committed against the King's family in Vietnam. Rust didn't choose to leave Alaska, his father sent him to the relative safety of Texas after training him how to survive the relentless onslaught of the King in Yellow's vengeance. Then, as the investigators stated, Mr. Cohle vanished from the map (the first step in the King's ultimate plan).
After the ‘accident’ involving Rust's daughter (orchestrated by the King in Yellow), Rust knew he had to disappear or face certain death so he chose to go deep cover, finding that to be a safer way to live than be out in the open without a badge where he would be easy for the King in Yellow to pick off. Once, Rust was allowed to resume normal life and take a job as a detective in the Louisiana State Police, the King in Yellow relocated to Louisiana, opened a Vietnamese restaurant as a front to avoid suspicion, and began gaining the loyalty of local criminals by offering them a direct line to his narcotic connections in Southeast Asia. The Lange murder and the cult sculptures are simply breadcrumbs the King in Yellow is using to lure Rust into a trap and finally finish his ultimate quest for revenge.
