David Twigg death: Fiancee 'visited parents after killing'
A woman who now admits murdering her fiancee visited his parents the following day and denied knowing what happened to him, a court heard.
Julie Dixon, 43, claims she killed David Twigg as part of a suicide pact.
He died after inhaling smoke when he was locked in a cupboard at his joinery workshop in Burgh le Marsh, near Skegness, which was then set alight.
A Newton hearing is being held to decide Dixon's motive and version of events.
In a statement read out at Lincoln Crown Court, Mr Twigg's mother Janice Twigg described how Dixon came to her Skegness home on 14 March, the afternoon she learnt of her son's death.
Dixon said injuries to her face were caused by intruders, the statement said.
A week later Mrs Twigg and her husband Roy received a letter in which Dixon claimed she and their son had been about to tell them of their plans to get married next year.
Dixon, previously of Station Yard, Burgh le Marsh, initially told police intruders were responsible for Mr Twigg's death.
She admitted the murder on the second day of her trial at Lincoln Crown Court last week.
Dixon will be sentenced following the Newton hearing.
