In 1954, Nurse Catherine Cooper (64) lived and worked in Limerick city as a home sister, visiting the ill and infirm at their bedsides. She was originally from County Clare, but had spent much of her working life in London, until the outbreak of World War Two.

On the night of November 19th, 1954, she decided to walk back to her hospital from her last home visit. On the Dublin Road, she was spotted by a 24 year old carman, Michael Manning, who had been drinking all day. He attacked her, and she was killed on the roadside.

But was Manning legally responsible for her death?
