This is a free summary of the sentencing hearing of James McKenna, who tried to stab his former to death in a park
A man who armed himself with a large kitchen knife and set out to track down and kill his former partner after she ended their relationship has been sentenced.
James McKenna repeatedly stabbed Joanne Sidaway after ambushing her as she walked her dog in park in Carmarthen. He then left her to die in the bushes and went on the run.
McKenna later accepted inflicting grievous bodily harm denied attempted murder – saying he had not intended to kill Miss Sidaway – but was convicted by a jury. During the trial at Swansea Crown Court jurors heard it was only by “pure luck” that Miss Sidaway survived the knife attack, which saw the defendant stab her 11 times.
The 58-year-old returned to the dock today to be sentenced. You can read our coverage of the sentencing hearing as it happened on this blog.
