Elizabeth Wettlaufer, the cat-loving Canadian nurse kept a sinister body of work online: nearly two dozen, often creepy poems - including one where she professes to love the "smell" of old folks. Wettlaufer, 49, of Ontario, intentionally administered fatal doses of drugs to her victims, aged 75 to 96, between 2007 and 2014. After killing, she would post some of her dozens of verses on a poetry website. One gory poem entitled Inevitable is written from the perspective of a knife-wielding female killer.
