A man battered his wife to death with a hammer before killing himself with a kitchen knife, an inquest has heard.

The bodies of Jonathan and Derisa Trenchard, who had been married for 24 years, were found at their home in Carbis Bay, last October.

The inquest in Truro heard that Trenchard, 50, had become paranoid and was under the belief that his wife was having an affair. However, following an investigation by police officers, who checked Mrs Trenchard's phone and the couple's computers, there was no evidence found that this was the case.

Mr Trenchard had spoken to his GP and was having counselling for depression and irrational thoughts

The inquest heard that the marriage had seemed happy and that the couple were devoted to their three sons.

Coroner Dr Emma Carlyon returned a verdict of unlawful killing after hearing from pathologist Dr Amanda Jeffery who said she did "not believe it to be a suicide pact."
