A chef and a waitress who were killed in a car crash were discovered dead by a friend who used a mobile phone tracking app to find them when they went missing, an inquest heard. Caleb Horncastle, 23, was killed alongside Holly Poyner, 17, when he lost control of his Mini Cooper while driving with his arm in a plaster cast. The two friends were found in the wreckage of the vehicle which ended up in a field near Hereford on July 23 last year.
