求翻译：As his name suggests, the serial killer known as Boston Strangler operated in Boston, Massachusetts area and murdered his victims by strangulation. He is believed to have murdered as many as 13 women, even though there are still many unanswered questions and guesses. It is possible that only (if you can really use that word) 11 women were actually murdered by the Boston Strangler. The killing started with strangulation of a 55 year old Anna Slesers on June 14, 1962 who was sexually molested by vaginal insertions of foreign objects and then strangled to death with her bathrobe cord. The last victim of Boston Strangler was murdered on January 4, 1964, which means he only operated for one and half year. Her name was Mary Sullivan 是什么意思？
