Trevor Edwards and his sweetheart Elsie Cook came from the same Welsh mining village of Cynon Valley. On Sunday morning, 17 June, a man rushed to the local police station and told them that he had seen a man bleeding heavily from the neck.

Officers investigated and the blood soaked man told them that he had killed his sweetheart and that she was lying on a nearby hillside. He admitted cutting her throat with a razor.

He was tried at Glamorgan Assizes before Mr Justice Branson on 22nd November and pleaded insanity. It was shown in court that his family had a history of insanity and that his father had died in a local asylum.

Despite all the evidence to support the insanity plea, the fact that Edwards had seemed perfectly sane when he confessed to the murder weighed against him and he was sentenced to death.

He was hanged by Robert Baxter and Alfred Allen. Allen was a new assistant, participating at possibly his first execution, and he was involved in a dramatic experience. Baxter was very quick in noosing the prisoner and pushing the lever.

Unfortunately for Allen, he was not able to get clear of the doors and followed Edwards into the pit. No blame was attached, and the Governor claimed the accident was a mixture of the hangman's alacrity and Allen's slightly defective vision.

The sentence had been carried out in Swansea on the 11th December 1928 with Edwards being only twenty years old.
