The whole story was investigated and the fact established. Dimnus stabbed himself on the spot, but Philotas, while acknowledging his carelessness, nevertheless denied that he had had any part in the plot and agreed to leave judgement concerning him to the Macedonians. After many arguments had been heard, the Macedonians condemned Philotas and the other accused persons to death. Among these was Parmenion, he who seemed to be the first of Alexander's Friends; he was not with the army, but it was thought that he had contrived the conspiracy by means of his son Philotas. Philotas, then, was first tortured and confessed to the plot, and then was killed in the Macedonian manner with the other condemned persons.
