The body of a murdered model who was last seen at Leytonstone Tube station was dumped in Buckinghamshire after probably being killed elsewhere, police have said.
The burning corpse of Beata Bryl was found in woods at Wooburn Green in July 29 2006.
The Polish national was caught on CCTV at Leytonstone station the previous day, where she boarded a westbound train.
Police have re-launched an appeal for information eight years after her murder.
Det Insp Colin Seaton said no link had yet been found between Miss Bryl and Buckinghamshire.
The 23-year-old had worked as a model in Germany. She was later employed in London as a waitress.
"We have not managed to establish any sort of link between Beata and Buckinghamshire," said Det Insp Seaton.
"We hypothesise that Beata's body was taken from somewhere else and that was the actual deposition site where her body was left."
