https://www.mangago.me/read-manga/brutal_satsujin_kansatsukan_no_kokuhaku/ - the uploader kind of cross-posted so read this one until the latest chapter.
https://www.mangago.me/read-manga/doom_satsujin_keisatsukan_no_danzairoku/ - this is where the uploader will upload the future chapters for Doom!
