dissenting in part.
I concur in affirming the judgment of conviction. However, I cannot join my colleagues in upholding the indeterminate life sentence pronounced in this case. Considering the circumstances of the offense and the offender, this sentence is the most ex*910treme that we have been asked to review in similar cases. I believe the sentence will result in confinement longer than necessary to accomplish all of the sentencing purposes. Therefore, I respectfully dissent from that part of the opinion which upholds the sentence.
