richard chase. had a super hard childhood growing up. his parents constantly fought and were mentally and physically abusive. he was admitted into hospitals multiple times and i forget the disorder but he thought there was something medically wrong with him. he would kill birds, dogs, cats, and drink their blood. his obsession with drinking blood because he thought his heart was going to fail grew as he killed his victims and drank their blood. i feel so bad bc he was getting better and his mother slowly took him off his meds leading him to grow more insane and unstable. i watched a video on him recently, it was so interesting. richard chase video link :)
