Between February 1964 and February 1965, the bodies of six women were found in or near the River Thames in west London. All had worked as prostitutes, all were found undressed, and most appeared to have suffocated rather than to have died of obvious violence.
The victims were Hannah Tailford, Irene Lockwood, Helen Barthelemy, Mary Fleming, Frances Brown and Bridget O'Hara. Two earlier deaths, in 1959 and 1963, are sometimes linked to the same man.
Newspapers called him Jack the Stripper, and the killings became known as the Hammersmith nude murders.
Forensic scientists found tiny flecks of spray paint on several of the bodies. The particles were traced to a covered area near a paint workshop on an industrial estate in Acton, which suggested the killer had kept the women there before moving them.
Scotland Yard, under Chief Superintendent John Du Rose, interviewed thousands of men and watched the area at night. After O'Hara, the killings stopped.
Du Rose later said his leading suspect had taken his own life, but the man was never named in court and the claim has been disputed by other researchers.
No one was charged, and much of the original evidence has since been lost or destroyed.
