I thought Chef Kai had worked for MICHAEL several months previous to June, then left, and returned a month or 2 before June 25th. Something about the chef that came in after she first left didn't work out, can't remember why though. I know I saw it or read it somewhere, but where, who knows. She was interviewed several times, maybe it was one of her interviews where she said it. Also, I vaguely remember her mentioning that she had met CM prior to her return, or something along those lines.
It's so hard to pinpoint who reported what at this point considering the volumes of reporting that's been done, and who was doing the reporting.
Kai had worked with Michael the first of the year, and was interviewed by the children. She said after a few months, she was let go because of salary issues. Then she had come back at the request of Michael because he knew that she could cook healthy foods that would give him energy. She said when she had come back she didn't know if there had been a previous chef, but she could tell that Michael had lost weight, but said she believed it was because he was rehearsing so much and forgetting to eat properly. Honestly, Kai is just a chef who happened to be working for Michael when he died and took it as a chance to help her expand her company.
