State is not required to present at preliminary hearing proof of every element of every offense charged. As State presented sufficient evidence for requirements of Section 111-2(f) of Code of Criminal Procedure, court erred in dismissing counts of being an armed habitual criminal, unlawful use of a weapon by a felon, and unlawful use or possession of a weapon by a felon; dismissed counts arose from same conduct as aggravated vehicular hijacking and armed robbery counts of preliminary hearing. (HOFFMAN and DELORT, concurring.)
