Whatever his motive, Dinis did not encourage the grand jury to get involved after the inquest. At the insistence of Foreman Leslie H. Leland, a pharmacist, the grand jury was reconvened in April 1970. But it was muzzled by Dinis' reluctance to press the investigation and by a court order prohibiting the jurors from summoning witnesses who had already testified at the inquest and from examining the inquest transcript. The grand jury quit in frustration, and Dinis declared: "The case is closed."
But public interest continued, as well as rumors about what really had happened. According to one theory, Kennedy delayed reporting the accident so that he could sober up. Another was that he had talked Gargan into taking the rap but changed his mind the next morning.
According to still another, Kennedy got out after running into Look and, fearful that Look was following, sent Mary Jo on alone in the car. The facts may well be far different from any of these theories. For five years, Kennedy kept silent, apparently hoping that the public memory of Chappaquiddick would fade. It did not.
