 Frederick Bailey Deeming was born on 30 July 1853 . At 16 years of age he ran away to sea , and thereafter , he began a long career of crime , largely thieving and obtaining money under false pretences . He was responsible for the murder of his first wife Marie , and his four children , at Rainhill , England , on or about 26 July 1891 , and a second wife , Emily , at Windsor , Melbourne , on 24 December 1891 . Less than three months elapsed between the discovery of Emily Mather ’ s body in Windsor , Melbourne , in March 1892 , and Deeming ’ s execution at the Old Melbourne Gaol for her murder in May 1892 ; a remarkably short time by comparison to modern western legal standards . After his execution , it was reported that over 12 @,@ 000 people cheered on the streets outside , and there was public speculation that Deeming was in fact Jack the Ripper .
