( People v. DeSavieu (1970), 120 Ill. App.2d 45, 256 N.E.2d 80.) Defendants also contend that the identification by the complaining witness when set off against the testimony of defendants' alibi witnesses raises a reasonable doubt as to defendants' guilt. ( People v. Prinsen (1969), 113 Ill. App.2d 363, 252 N.E.2d 101.) People v. Prinsen is wholly distinguishable from the case before us since there the complaining witness had bad eyesight and offered testimony of an unconvincing nature.
