Did Marilyn see anyone that day?

Multiple accounts show that Marilyn had people come to the house such as Lawrence Schiller, Agnes Flanagan and that she went to the beach near Peter Lawford’s home. However Schiller’s claims have changed over the years. He also later claimed that Marilyn had Bobby Kennedy at the house. Which is false. The Agnes Flanagan account came from a third party so cannot be confirmed. Marilyn going to the beach is unlikely as she spent the day in her dressing gown or house coat.
