Reply #14: The reasons that have been speculated....

[Robeson]

...come from the fact that John Tower, Head of the Tower Commission, which investigated the Reagan Adminsitrations dealings with the Iran Contra affair, died in a plane crash. Heinz, also, investigated Iran Contra. Both died in separate plane crashes 1 day apart from each each other. Speculation is that they retained important documents from their work on these matters. Also, it is thought by some that both Tower and Heinz were involved, and/or knew of Bush, Sr.'s, engineering of the delay of the release of the Iranian hostages, so that Reagan could be assured of victory in the 1980 election. Again, that name "Bush" just keeps popping up....

If the above speculations are true, then certainly there would have been plently of motives to eliminate Heinz from the scene. Dead men tell no tales...
