DNA ‘linked to accused’ on World’s End victim
Jurors have already been told that Angus Sinclair claims Helen Scott and Christine Eadie, both 17, were “alive and unharmed” when he left their company.
The girls were last seen at the World’s End pub in Edinburgh on 15 October 1977.
Sinclair, 69, is on trial at the High Court in Livingston where he denies raping and murdering the girls.

He is accused of carrying out the attacks along with his brother-in-law, Gordon Hamilton, who is now dead.
Earlier this week jurors heard Sinclair’s version of events, described as his “recollection”, when a section of a defence report was read to the court.
It stated he had “consensual sexual intercourse” with Christine followed by Helen, and that Hamilton had “sex with both girls in the opposite order”.
Sinclair then claims that Hamilton drove him back to East Lothian as he wanted to continue fishing. He said the girls were alive when he left.
The report was read out during the evidence of forensic scientist Geraldine Davidson.
During her third day of giving evidence, she talked through DNA analysis carried out on pants found beside Helen’s head when her body was discovered.
One of the areas was on the outside front left-hand side which revealed a mixed DNA profile. She said, in her opinion, Sinclair could have contributed to this profile.
The results were sent for further analysis and there was “extremely strong support” found for both Sinclair and Hamilton to be contributors.
Ms Davidson was asked by Lord Advocate Frank Mulholland, prosecuting, to discuss her findings in relation to the gusset area.
She told the court that the absence of a significant amount of DNA evidence in that section did not fit with the underwear having been put back on and worn after sex.
The findings could support the suggestion that the teenager had not put her underwear on after intercourse, the witness said.
Defence QC Ian Duguid has not yet had the opportunity to question her.
Sinclair denies the charges against him and has submitted three special defences: incrimination alibi and consent to sexual intercourse.
The trial continues.
