Gertie Jensen's was attacked and left at a Gothenburg demolition site

On August 12, 1980 at seven o'clock in the morning, Gertie Jensen's naked body was found at a Gothenburg demolition site.

Gertie Jensen, 31, was a drug user and a part-time prostitute. She had been viciously hit on the back of the head with a brick.

Following the murder of Teresa Thorling at the end of August police departments from Gothenburg and Malmo started comparing notes about the killings while individually trying to solve their cases. Malmo interviewed Teresa Thorling's boyfriend and the other sex workers who saw her alive last.

Reports initially led police to investigate whether Peter Sutcliffe had ever travelled to Sweden after records listed him and his lorry on a ferry bound for Sweden.

Swedish police were contacted by DCI Dunkerley who was leading the Yorkshire Ripper cold-case review.

DCI Dunkerley said that he was absolutely certain that Sutcliffe had never been in Sweden.The telex that Operation Painthallhad originally written about described nothing more than a rumour. As far as he was concerned, the case was closed.
