A large piece of shrapnel in an injured prison officer's leg was a 'major significant factor' in his death, a jury in a murder trial has heard.
The former state pathologist was giving evidence at the trial of a west Belfast man accused of murdering Adrian Ismay.
Professor Jack Crane, who carried out the post-mortem, told the diplock style non-jury trial that the piece of shrapnel, which was found deep in the muscle behind his left knee, contributed to the prison officer’s immobility and led to a large clot moving into his heart and one lung.
The 52-year-old father-of-three died of a pulmonary embolism eleven days after a bomb partially exploded under his van near his home in east Belfast in March 2016.
Belfast Crown Court heard Mr Ismay, who suffered multiple superficial shrapnel wounds to his legs and his eye, was diagnosed with post traumatic stress disorder by his GP the day before died.
Christopher Alphonsus Robinson, 48 and from Aspen Park in Poleglass, denies the murder, possessing explosives and providing the car used in the attack.
The trial continues.
