Just noting:
“In answer to questions about his parents’ home life, Jonathon said they had not slept in the same room for 10 years; but he had no concerns about infidelity in their marriage and did not think his parents would ever get divorced.
“According to Jonathon, his parents had a private relationship and a public relationship. In public they were the world’s greatest power couple, however, in private they did not get along. When the children were younger, there was a lot of shouting and yelling in the house. Over the past five years their relationship got a lot better, possibly because the children had grown up,” the detective notes in his summary of Jonathon’s witness statement.”
