Monday marked the 40th anniversary of the death of Marilyn Monroe, who died at the age of 36, and the day did not go unnoticed by fans. More than 200 people — including many who were too young to have remembered Marilyn while she was alive — attended a memorial service in a chapel at Los Angeles’s Westwood Village Memorial Park, reports the Associated Press. Loudspeakers had to be set up outside in order to handle the overflow crowd, reports the news service. The largest floral arrangement at the service came from the screen legend’s close friend Robert Slatzer, author of “The Life and Curious Death of Marilyn Monroe” and who, like many of Monroe’s fans, has never been satisfied with the officially listed cause of death. The coroner said it was suicide, though over the years several unconfirmed theories have emerged, including that she was drugged by the Kennedys in order to keep her affairs with Jack and Bobby Kennedy quiet. At the Westwood service, 40 white long-stemmed roses formed a large wreath and framed a black-and-white photo of a pensive-looking Monroe. Slatzer told the AP that he snapped the picture of his “best drinking buddy” after she had a particularly long day of filming on the set of “Something’s Got to Give” in 1962. The unfinished film, costarring Dean Martin, would have been Monroe’s 31st.
