Mary Jo Kopechne had been dead for several months when her parents began to have serious questions about what had really happened the night of July 18, 1969.
At first, Gwen and Joe Kopechne had believed Senator Ted Kennedy’s account of that evening after his car had plunged off the narrow wooden bridge on Chappaquiddick Island, just off of Martha’s Vineyard, landing upside down in a tidal pond with their daughter trapped inside. “They trusted him,†says Mary Jo’s aunt, Georgetta Potoski, 75. “They loved the Kennedys. Everyone did. But later on, they started to question what happened.â€
Kennedy escaped from the car and later testified that he had tried to save Mary Jo, an idealistic 28-year-old who had worked for his brother Bobby and was in Chappaquiddick for a reunion party of her fellow campaign workers. But Ted could never escape the unanswered questions about his 10-hour delay in reporting the accident to Edgartown police.
