In a letter Mr Morgan wrote to his current wife in 2019, after they had been arrested, he said: “Trust works on both side. If I didn’t trust you, you wouldn’t be here and I would not.”
The jury was also played secret police recordings of conversations between the couple when they were being taken in for questioning in 2019.
Margaret Morgan was heard to say “Shush”, indicating she thought they were being taped. He said: “I am sorry” and “I don’t want to say anything because they might have…”
Two years later, on 1 July 2021, he was recorded asking her: “Do you still love me?” and “I trust you forever.”
Then, on 25 July 2023, as they were travelling again to the police station, he said: “I am sorry. I haven’t done anything.”
She replied said: “Stop going over it. They are probably listening in.”
Allen Morgan said: “I ain’t done nothing. Neither of us have. I don’t know what they have got.”
She replied: “Well, they must have something.”
The prosecutor said: “The defendants planned and agreed the murder of Allen’s first wife, Carol. They were tied to each other – each with the power to bring the mutual destruction of a criminal prosecution on each other.
“There was an unbreakable bond based on their joint responsibility for the killing of Allen Morgan’s former wife.”
The case continues.
