Sorry, I was wrong, although I sure thought that was what happened. Here is the wikpedia lowdown: Mary Jo Kopechne which has a couple of other odds and ends, including questions on the cause of death.

Bobby Baker scandal
During her tenure as Senator Smathers' secretary, Mary Jo shared an apartment flat with Nancy Carole Tyler, secretary to Bobby Baker, an aide to Vice President Lyndon B. Johnson. An emerging scandal involving Baker's corrupt activities prompted President John F. Kennedy to privately offer Senator George Smathers the second spot on the 1964 presidential ticket with plans to drop Johnson as his running mate. The roommates, Kopechne and Tyler, allegedly leaked the President's plans to the press. Some researchers have claimed a link between the Bobby Baker scandal and the 1963 JFK assassination. Tyler died mysteriously in a plane crash in May 1965. Kopechne went on to become secretary to Senator Robert F. Kennedy, until he was assassinated in June 1968 during his run for Presidency.
More tidbits. Maybe it was Arkanside before there was Arkanside?
Oh, I see that you said it was wrong. Sorry for the second post.
