A jury at Caernarfon Crown Court heard today that John Yates beat and sexually assaulted his wife Barbara, seven months before her body was found in the boot of his car.
A friend of 49-year-old Barbara Yates said she saw her in hospital in December 2011 with "horrific injuries."
Mr Yates was arrested, but his wife withdrew her complaint, the court heard.
The 58-year-old from Warrington admits manslaughter, but denies murdering his wife.
Her body was found in the boot of his car outside the police station in St Asaph last July.
The trial continues.
