Patterson informed the group that she wished to debate a medical concern she was having and whether or not to inform her youngsters, who weren’t current through the meal. After Simon pulled out the night time earlier than, she expressed her disappointment in a textual content, writing: “I wanted it to be a special meal, as I may not be able to host a lunch like this again for some time.”
Wilkinson later testified that Patterson informed the company at lunch that she had been recognized with most cancers.
The prosecution mentioned medical information confirmed no such analysis, and accused Patterson of mendacity as a pretense for the adults-only meal.

By that time, the household had completed their meal. Patterson had made every of the company their very own particular person beef Wellington pastry, and served herself on a plate that was a distinct measurement and coloration than the opposite 4.
