Stewart 'thought about suicide' before her arrest
In the six interview tapes played to the court yesterday Ms Stewart (47) also told police:
- Howell (51) tried to convince her to go along with his murder plan by telling her that her abortion proved she could kill.
- She confronted Howell and told him to get out of the house when he arrived to kill her husband.
- She thought Mrs Howell was very confident, entertaining, clever and a good mother.
- After they resumed their relationship after the killings, she went berserk when she feared Howell had given her too much laughing gas before a sex session on his dentist's chair.
- Killing their spouses did not seem to bother Howell and he acted like it was just another day.
- Ms Stewart said she thought about killing herself before police came to arrest and question her about the killings.
- She also told investigating police officers that she never planned to have a new life with Howell even though he wanted to marry her.
- Ms Stewart said she was in love with him in the early months of the relationship but after the killings her feelings changed.
Ms Stewart told the police the pair had talked about carrying out the killings but she added there was nothing in it for her.
"I had nothing to gain. I had nothing to gain by him doing that. I didn't have anything to gain.
"I wasn't very good in my marriage but I had nothing against Trevor. We had good times. There wasn't a problem but I had nothing to gain," she said.
"Obviously he (Howell) had other plans for himself. But it wasn't including me. In one way he thought maybe I would go with him and get married. There was no intention of that. I never said I would marry him, never."
She also told police that the relationship, after the deaths, was not natural or normal. She said she wanted their sexual relationship to stop but Howell was frustrated and he wanted to make her more relaxed.
"It was so strained. I didn't want him. He scared me. I didn't want anything to do with him," she said.
It was years, she went on, before she ever went near the row of houses in Castlerock, known as the Twelve Apostles, where the bodies were found.
