Derrick Shareef withdrew a previous withdrawal of a guilty plea. That means his original guilty plea stands.
Shareef was arrested in December, 2006. Prosecutors say he was trying to buy grenades and a handgun from an undercover FBI agent which he planned to use in an attack on Rockford's Cherryvale Mall during the 2006 holiday season.
Investigators say he told an informant he wanted to commit acts of violent jihad against civilians.
