In October 2007, the commission released its report and recommended that the case be re-opened. They concluded that the case had been seriously marred from the start by tunnel vision. In particular, the same persons, chosen from close circles of the hospital authorities rather than on the basis of recognised relevant expertise, had first helped the hospital in its internal investigations, then had advised the police, and finally had appeared before the courts as independent scientific experts. They noted that there was strong disagreement concerning whether or not baby Amber had died of digoxin poisoning. On 2 April 2008, de Berk was released for three months because after re-examination of the death of the last "victim", a natural death could no longer be ruled out.
