World’s End serial killer Angus Sinclair dies in prison aged 73

World’s End serial killer Angus Sinclair has died aged 73.

The notorious Scottish murderer, who was convicted of killing four girls, passed away in Glenochil prison this morning.

The monster was one of the country’s longest-serving prisoners, having been locked up continuously since 1982.

He had previously been sentenced to 10 years behind bars, in 1961, for killing seven-year-old Catherine Reehill.

He later carried out the World’s End murders – although he was tried twice, after initially being acquitted of the crimes.

Christine Eadie and Helen Scott were raped and murdered after a night out at the World’s End pub in Edinburgh in October 1977.

The pair were both only 17, with their bodies found six miles apart in East Lothian, the Daily Record reports.

They had been gagged, beaten, raped and strangled.

Despite DNA evidence linking him to both of the teenagers, Sinclair was acquitted of the murders.

The judge ruled that there was no case to answer.

But in 2014, Sinclair was tried for the second time following the introduction of the Double Jeopardy (Scotland) Act in 2011.

By this point, he was already serving life sentences.

He had been jailed in 1978 for the murder of Mary Gallacher at Barnhill Rail Station in the north of Glasgow.

During the second trial, jurors visited the World’s End murder scenes and Sinclar was convicted of the killings.
