An inquest into the deaths of three army reservists will begin on Monday June 1. Llandudno man Craig John Roberts, 24, Edward John Maher and James Dunsby, both 31, collapsed during an army training exercise. On July 13, 2013 on one of the hottest days of the year, as temperatures reached 29.5C (84F), emergency crews were called to Pen y Fan, the highest mountain in the Brecon Beacons in Powys, Mid Wales when six soldiers had collapsed suffering heat exhaustion. Witnesses said they had seen soldiers looking exhausted and pleading for water during the gruelling exercise.
