The trial of a 62-year-old man accused of raping and murdering two teenage girls nearly 30 years ago has got under way at the High Court in Edinburgh.
Helen Scott and Christine Eadie went missing after a night out
The case became known as the World's End murders because the girls went missing after a night out at a pub of the same name in the Scottish capital.
Angus Sinclair has denied attacking and killing Christine Eadie and Helen Scott, who were both aged 17.
Their bodies were found in separate places in East Lothian in October 1977.
Mr Sinclair has lodged a special defence incriminating his brother-in-law Gordon Hamilton, who is now dead.
Judge Lord Clarke told the jury of nine women and six men that they must reach their verdicts on the evidence alone.
"The various charges are alleged to have been committed almost 30 years ago. That makes it an unusual situation," he said.
