"Christa Worthington (December 23, 1956 – January 6, 2002) was a United States fashion writer who worked for Women's Wear Daily, Cosmopolitan, ELLE, Harper's Bazaar, and The New York Times. She was also a co-author of several books on fashion and formerly dated Stan Stokowski, the oldest son of Gloria Vanderbilt and Leopold Stokowski.
Worthington was stabbed to death at her home in Truro, Massachusetts (on Cape Cod). Her body was found on January 6, 2002, with her two-year-old daughter, Ava, clinging to it. The child was unharmed. On April 15, 2005, a local garbage collector, Christopher McCowen, was arrested and charged with her rape and murder. On November 16, 2006, he was found guilty in Barnstable Superior Court of first-degree murder, rape and burglary, and sentenced to life without parole. In January 2008, a hearing was held due to three jurors' separate allegations that racism was involved in the deliberations. In December 2010, the Massachusetts Supreme Judicial Court denied an appeal for a new trial..."

"Mary Mallon (September 23, 1869 – November 11, 1938), also known as Typhoid Mary, was an Irish-American cook. She was the first person in the United States identified as an asymptomatic carrier of the pathogen associated with typhoid fever. She was presumed to have infected 51 people, three of whom died, over the course of her career as a cook. She was twice forcibly isolated by public health authorities and died after a total of nearly three decades in isolation.
Among the infections Mallon caused, at least three deaths were attributed to her; however, because of her use of aliases and refusal to cooperate, the exact number is not known. Some have estimated that she may have caused 50 fatalities.
Mallon was the first asymptomatic typhoid carrier to be identified by medical science, and there was no policy providing guidelines for handling the situation. Some difficulties surrounding her case stemmed from Mallon's vehement denial of her possible role, as she refused to acknowledge any connection between her working as a cook and the typhoid cases. Mallon maintained that she was perfectly healthy, had never had typhoid fever, and could not be the source. Public-health authorities determined that permanent quarantine was the only way to prevent Mallon from causing significant future typhoid outbreaks.
Other healthy typhoid carriers identified in the first quarter of the 20th century include Tony Labella, an Italian immigrant, presumed to have caused over 100 cases (with five deaths); an Adirondack guide dubbed "Typhoid John", presumed to have infected 36 people (with two deaths); and Alphonse Cotils, a restaurateur and bakery owner.
Today, "Typhoid Mary" is a colloquial term for anyone who, knowingly or not, spreads disease or some other undesirable thing..."
