And where intent is an element of a crime, it must be proved by the State beyond a reasonable doubt. ( People v. Broccolo, 7 Ill. App.3d 1009, 288 N.E.2d 883 (abstract opinion); see People v. Friedman, 321 Ill. 572, 152 N.E. 523; compare People v. Long, 385 Ill. 495, 53 N.E.2d 446.) Of course, it may be shown by circumstantial evidence. ( People v. Beacham, 358 Ill. 373, 193 N.E. 205; People v. Walker, 21 Ill. App.3d 202, 315 N.E.2d 244; see People v. Minish, 19 Ill. App.3d 603, 312 N.E.2d 49.) But where, as in these cases, a conviction is based on circumstantial evidence, the evidence relied on must produce a reasonable and moral certainty that the accused is guilty of the crime charged.
