A TRAINED first-aider who admitted killing his wife during a kinky sex game could not remember what to do when she stopped breathing, a murder trial heard yesterday..

Norman Heaton, 32, throttled mother-of-three Jacqueline Heaton with a length of washing line before hiding her lifeless body under the stairs of their masionette in Anderson Street, South Shields, South Tyneside, Newcastle Crown Court was told.

The jury heard that the couple, who had recently moved to Tyneside from Crook, County Durham, had been due to split up on the day of her death after a series of rows.

But during their last passionate session together on May 2, last year, Mr Heaton told police in an interview he couldn't remember what to do when she stopped breathing.

Mr Heaton had twice been trained in first aid by the St John Ambulance Service, in 1997 and 1998, but failed to carry out first aid on his wife.

The court also heard how during sex games Mr Heaton watched for her blacking out and watched for her eyes to go red, then released the rope.

The court was also told how Mr Heaton had planned to snatch his children the night before the killing and to take them to London so Mrs Heaton and her mother could not poison them against him.

He had the children's birth certificates in a carrier bag and compiled a list of what to do and how to get money for food.

Mr Heaton denies murder and the trial continues.
