The 3rd of August was the hottest day 1990 and County Durham had seen so far. That Friday would end up being the hottest day ever recorded in England at the time. So, when it came time for Peter Heron to come home for lunch to the fairly rural property on the outskirts of Darlington that he shared with his wife Ann, he was not surprised to find that she has been sunbathing in the yard. He would leave again an hour later, back to the office for meetings as Ann moved her sun lounger around to the front of the property, to enjoy the rest of the afternoon sun. A few people reported seeing Ann lounging in the yard as their vehicles passed by on the busy A67 — Darlington to Yarm Road. But when Peter returned home just before 6 that evening, he would find his wife murdered on the living room floor.
