This has been somewhat of a hot topic since the mid-sixties and it shows no signs of cooling. Opinion in general these days leans toward the theory that RFK engineered her death and was present at the time of it.
There are some however, who feel that Marilyn's death was an attempt to frame RFK and various names have been put forward over the years as culprits for this. The mob in particular have been named as likely suspects because of RFK's crackdown on their activities and because of Joe and Jack Kennedy's reneging on alleged electoral promises to Giancana.
A number of researchers, most notably perhaps Donald H Wolfe and Robert Slatzer, have concluded that RFK was involved, though there are inconsistencies in their published research which have led some to conclude that they have been selective in presenting their findings or have been subjective in interpretation.
I'd be interested in opinions on this topic.
