Gaius Gracchus also came under suspicion. However, "this great outrage, committed too upon the person of the greatest and most considerable man in Rome, was never either punished or inquired into thoroughly, for the populace opposed and hindered any judicial investigation, for fear that Gaius should be implicated in the charge if proceedings were carried on". Gaius Papirius Carbo also came under accusation. During a trial Lucius Licinius Crassus accused Carbo of being a party to the murder of Scipio. Ian Worthington rejects all these speculations and argues that Scipio Aemilianus died of natural causes.
