10. Montague John Druitt
Montague John Druitt (15 August 1857 – early December 1888) was a Dorset-born barrister who worked to supplement his income as an assistant schoolmaster in Blackheath, London, until his dismissal shortly before his suicide by drowning in 1888. His decomposed body was found in the Thames near Chiswick on 31 December 1888. Some modern authors suggest that Druitt was homosexual, that he was dismissed because of this and that it may have driven him to suicide. However, his mother and his grandmother both suffered mental health problems, and it is possible that he was dismissed because of an underlying hereditary psychiatric illness. His death shortly after the last canonical murder (which took place on 9 November 1888) led Assistant Chief Constable Sir Melville Macnaghten to name him as a suspect in a memorandum of 23 February 1894. However, Macnaghten incorrectly described the 31-year-old barrister as a 41-year-old doctor.
