CHILD killer Robert Black smoked heavily for half a century before suffering a fatal heart attack, an inquest heard.
The former delivery driver, who murdered four schoolgirls between 1981 and 1986, was found dead in his cell in HMP Maghaberry in Northern Ireland in 2016, aged 68.
He had high cholesterol and smoking is likely to have damaged his coronary artery, GP Dr Joseph Palmer told an Armagh court.
Black (pictured) had smoked for 51 years and did so until his death, despite complaining of angina chest pains. He also suffered a stroke 20 years previously. The inquest continues.
