Child killer Black, 68, died of heart attack

SERIAL child killer Robert Black died from a heart attack, an inquest jury has confirmed.

The former delivery driver from Falkirk, who preyed on victims as young as five, was at serious risk after a lifetime of little exercise and heavy smoking.

Black was found dead in his cell in Maghaberry high-security prison in Co Antrim in January 2016, aged 68.

He murdered four schoolgirls between 1981 and 1986.

Jurors found he died from a cardiac arrest, with degeneration of the walls of the coronary artery a secondary cause.

They confirmed underlying factors included his age, his smoking and diet, high blood pressure, a previous stroke and diabetes.
