The estranged wife of the man accused of murdering two teenagers 30 years ago has been giving evidence at his trial.
Helen Scott and Christine Eadie went missing in 1977
Angus Sinclair denies raping and killing Christine Eadie and Helen Scott, both 17, in 1977 after a night out at Edinburgh's World's End pub.
His wife Sarah Sinclair, 57, waived her right not to give evidence at the High Court in Edinburgh.
In a special defence, Mr Sinclair has blamed his deceased brother-in-law Gordon Hamilton for the crimes.
Mr Sinclair is accused of carrying out the murders of the teenagers with Mr Hamilton.
Mrs Sinclair told the trial how her husband would go on fishing trips with her late brother, Mr Hamilton, which took up whole days.
She said she was legally separated from Mr Sinclair but they are still married.
Judge Lord Clarke told her that she was not legally obliged to give evidence at her husband's trial but she agreed to do so.
Mrs Sinclair said she married the accused in July 1970 after dating him for less than a year.
After living in the centre of Edinburgh, the couple moved to Glasgow, where they were living at the time the girls died.
The registered psychiatric nurse was asked a number of questions about her late brother Mr Hamilton.
She said they were brought up in Glasgow in a family of nine children and that her brother and husband spent time together.
The girls were last seen alive at the World's End pub
Advocate depute Alan Mackay asked about a Toyota Hiace caravanette, which her husband bought in June 1977.
"Did he use the vehicle for fishing trips to your knowledge?" Mr Mackay asked, and Mrs Sinclair said he did.
"Normally a weekend," she added. "It would be the whole weekend."
Mrs Sinclair also said her husband would take her on trips to East Lothian where the girl's bodies were found in separate locations.
The court went on to hear from Alex Parker, 67, who confirmed that his family car dealership in Stepps, North Lanarkshire, sold the caravanette to Mr Sinclair in June 1977.
He said that the accused then sold the vehicle back to the dealership the following year.
Mr Sinclair is accused of acting alongside his late brother-in-law, of persuading or compelling the girls into a motor vehicle, holding them against their will and raping and murdering them.
The trial is due to resume on Monday
