Suspect 'raped Miss Teen USA before murder' Mark Spatucci, 22 (left) is accused of murdering and raping his pageant-queen ex-girlfriend Mary Greff, 23 (right). A 22-year-old man accused of murdering his pageant-queen ex-girlfriend has now been charged with her rape. Mary Greff, 23, was discovered strangled to death in her parent's New Jersey, US, home last month. Her ex-boyfriend, Mark Spatucci, is accused of entering the home through the second-floor window and killing her while their infant son slept in the same room. Now prosecutors have added additional charges after an autopsy revealed Greff, a former Miss Teen USA contestant, had been raped before being killed. Spatucci pleaded not guilty to two counts of sexual assault and one count of felony murder in court yesterday. Greff's parents were believed to be asleep in another part of the house during the tragic incident. The couple reportedly began dating two years ago but split shortly after Greff had her baby.
