Did Kennedy and Mary Jo actually leave the party at 11:15 p.m., as he claims, in order to catch a ferry to Edgartown, or did they leave more than an hour later, after the ferry had shut down? Did Kennedy deliberately turn from the paved road leading to the ferry onto the dirt road toward the bridge?
Did Markham and Gargan return to the bridge and dive down into the murky water in efforts to recover the body? Did Kennedy really swim the channel to Edgartown, or did Markham, Gargan and Kennedy cross the channel together in a small boat they borrowed from a pier on Chappaquiddick? Or did Kennedy indeed make the impulsive swim, with Markham and Gargan following in a boat? Whatever the answers that emerge, all of the witnesses will have parts in one of the most extraordinary political and human courtroom dramas ever staged.
*Adding to Kennedy's burden of grief, his wife Joan last week suffered her third miscarriage. They have three children.
