Health officials reveal 84 HIV cases in 2017

how to carry out CPR (cardiopulmonary resuscitation) on Ms Reilly.

A paramedic, who attended the scene, told the inquest that on arrival Ms Reilly had “no pulse and was not breathing”.

Ms Reilly was formally pronounced dead around 10.45pm.

A post-mortem report compiled by Professor Jack Crane, the state pathologist for Northern Ireland, concluded that Ms Reilly had died from the effects of PMA, which included accelerated heart rhythm and high blood pressure.

The drug is also known to cause extremely high temperatures and convulsions.

Ms Reilly’s father, Kevin Reilly, told the inquest that he last spoke to his daughter the evening before she died.

“She was completely normal,” he said, stressing that he was “never aware of any drugs”.

“It was a complete shock,” added Mr Reilly.

Ms Reilly had been previously described as a caring person who loved working with the elderly.

At her funeral over five years ago, mourners heard that Ms Reilly would be remembered for her “beautiful smile” and had been “adored” by her elderly care patients.

Giving her ruling, the coroner said PMA had been “devastating” in the case of Ms Reilly, whose death had been a “terrible shock” to her family.

Offering her deepest sympathies to Ms Reilly’s parents, Ms Anderson said what had happened should serve as a warning to others.

“This highlights the very grave danger of taking illicit drugs,” she said. “There is no way of knowing what is in them or what effect they will have.”
