A mother who was killed by her son after he said he "lost it" over a disagreement about the purchase of an iPhone died after suffering six hatchet wounds to the head as she lay in her bed, a murder trial jury has heard.

The 28-year-old autistic man admits killing his mother "without any lawful justification" but expert psychiatrists for both the prosecution and defence are in agreement the accused was insane "as defined by law" at the time of his mother's death, the Central Criminal Court has been told.
