Defendant pled guilty on April 1, 1974, to a charge of kidnapping a 13-year-old girl and was sentenced on April 29, 1974, to a maximum indeterminate term of 20 years imprisonment. On direct appeal from the judgment of conviction, defendant contends that the trial court erred in accepting his plea. We hold that the trial court did not make sufficient inquiry to establish that there was a factual basis for the plea, and accordingly we reverse and remand.
