You should look up the Chandler Halderson case. The trial was live streamed last year I think. He killed, dismembered, (maybe had a taste), tried to burn parts of his parents in the fireplace, then discarded the remaining parts in various locations across Wisconsin. The reason that he killed them was that he had constructed an elaborate set of lies about jobs that he had, and university courses he was taking, including getting a job at SpaceX. Then his dad found out, so he shot him, then shot his mum when she came home. Then spent the next day or two cutting them up and cleaning up the blood. I reckon his girlfriend was in on it too, maybe an accomplice. Very fucking sus. The trial live streams were pretty entertaining as it was just a circus horror show.
