In a gripping trial unfolding at Swansea Crown Court, James McKenna stands accused of attempting to murder his former partner, Joanne Sidaway, in a shocking ambush at Carmarthen Park. The 57-year-old denies the murder charge but has admitted to wounding with intent and possessing a knife in public. The jury’s decision now hinges on one critical question: was there intent to kill?

Prosecution barrister James Wilson argued forcefully that McKenna’s vicious attack—stabbing Miss Sidaway 11 times—was not only premeditated but a clear attempt to end her life. Describing the incident as a “frenzied attack,” Wilson pointed out McKenna’s choice of weapon and his calculated ambush as evidence of his deadly intent.
After the brutal assault, McKenna fled the scene, hid in an allotment shed, and astonishingly, took a moment to eat yogurt before going into hiding. This behaviour, according to the prosecution, underscores his lack of remorse and consciousness of guilt.

On the other side, McKenna’s defence barrister, Caroline Rees, urged jurors to separate emotions from the facts. She challenged the perception of intent, questioning why McKenna would attack through clothing if he meant to kill. Rees suggested that wounds, although serious, were not necessarily aimed to kill, and pointed out that McKenna did not target more lethal areas.
As Judge Paul Thomas KC reminded jurors, it’s up to them to weigh the evidence without speculation, using common sense and reasoning rather than emotion. The trial resumes Monday, and everyone’s eyes are on what the jury will decide. Stay tuned for more updates as this intense courtroom drama unfolds.
