 Specifically, the case against defendant Angelo Buono was based largely on the testimony of co-defendant Kenneth Bianchi, who became uncooperative and unreliable, claiming to have multiple personalities and repeatedly changing his story.Van de Kamp was assured by his prosecutors that because of Bianchi's behavior, conviction of Buono could not be secured.Van de Kamp accepted their judgment and allowed the trial prosecutor, Roger Kelly, to move to dismiss all 10 murder charges against Buono and release him with an eye toward trying him for pandering.
