Killer dentist Colin Howell asked his ex-lover Hazel Stewart to marry him and start a new life in Scotland after he had murdered her husband and his wife.
Coleraine Crown Court heard yesterday that Howell and Stewart continued their affair for five years after the murders.
Crown prosecuter Ciaran Murphy QC said that Howell and Stewart resumed a sexual relationship just weeks after the funerals of their partners.
He said the relationship was conducted in secret for a while, but by 1994 he was taking his children over to her house and they had gone on holidays together to Newcastle, Co Down, and the Lake District in England.
The court was told that Howell had gone to Scotland on holiday and saw two dental practices for sale. He proposed to Stewart in 1995 and suggested that they resettle in Scotland but she said no.
Their relationship ended the following year when she began dating another man who she had met in the gym.
The court also heard that Stewart became pregnant to Howell the year before the murders. They both travelled to London where she had an abortion.
When Stewart ended the relationship, the court was told that Howell became angry.
Stewart told police: “He prowled the back of the house, he drove up and down, he wouldn't let me go, I was scared. He was angry.”
Stewart later married her second husband, retired police officer David Stewart.
Howell married his second wife Kyle. She has since filed for divorce.
