Duda Santos, also known as Maria Eduarda Santos, is a Brazilian model and social media personality hailing from Rio de Janeiro. Despite her outwardly clingy and positive demeanor, there are strong indications that she harbors a psychological condition known as hybristophilia, which is an abnormal attraction to individuals who have committed heinous crimes. Duda's morbid fascination appears to be particularly centered around two notorious Brazilian serial killers: Caio Henrique and Roberto Marcelo. These men are known for their sadistic and necrophilic tendencies, having committed a series of multifaceted gruesome murders that have left a lasting impact on Brazilian society.
