Husband Battered Wife To Death Over Affair Fears

An inquest has heard a St Ives man battered his wife to death then killed himself, after becoming convinced she was having an affair.
Jonathan and Derisa Trenchard were found in their Carbis Bay home last October.
The couple's two eldest sons said his behaviour had changed in the months leading up to his and their mum's death.
Work colleagues said he talked to himself about his suspicions, once saying if Derisa and their three boys left he would drive them all over a cliff.
In the end the 48-year old was urged to get medical help.
The hearing was told how the couple were devoted to their children and seemed happy.
In a written statement one of the couple's sons, Christopher, told how things began to fall apart during a trip abroad: "In June 2013 we went away on a family holiday to Lanzarote and it was during this holiday I became aware of some of the insecurities my father was feeling.
"He was not the most empathetic type of person but he chose to confide in me. He wanted to know whether I would be honest in telling him if I knew or would find out if my mother was having an affair with another person.
"I told him I would tell him but I also told him that he should not need to worry about this type of talk because I knew my mother loved him and would never have an affair, or look to change her marital situation.
"This conversation took me aback a bit because I have always seen dad as a positive and strong character and he was showing signs of insecurity and vulnerability.
"He went on to tell me that he believed she may be secretly liaising with someone on her phone and I again reassured him of the trust he always had in her. I know that my mother was not having a secret relationship or affair with another man."
It is thought those phone conversations may have been with her daughter from her first marriage.
Police found no suicide note - but did discover a lump hammer next to 50-year old Derisa's body.
Her husband has suffered a series of stab wounds to his chest. A kitchen knife was found nearby.
The coroner ruled Derisa Trenchard was unlawfully killed and Jonathan Trenchard took his own life.
There will now be an independent review, which is routine, to see if lessons can be learnt to prevent similar cases in future.
