The Denver Post reports that the Colorado Court of Appeals is scheduled Tuesday to hear the case of Amir Massihzadeh, who says he is entitled to the full $4.8 million jackpot rather than the $568,990 he was awarded in 2005.
The newspaper reports that 10 years later, Colorado Bureau of Investigation agents informed him that the other two winners were suspected of involvement in a criminal scheme to rig lottery results.
Lottery officials say Massihzadeh was locked into a contract when he signed the original ticket, although he was not suspected of wrongdoing while the other two were convicted.
