"An extra-judicial confession extracted in violation of constitutionally enshrined rights is inadmissible in evidence. During custodial investigation, suspects have the rights, among others, (1) to remain silent, (2) to have an independent and competent counsel, (3) to be provided with such counsel, if unable to secure one, (4) to be assisted by one in case of waiver, which should be in writing, of the foregoing; and (5) to be informed of all such rights and of the fact that anything he says can and will be used against him. Where the remaining pieces of evidence are insufficient to determine guilt with moral certainty, the appellant is entitled to an acquittal. A conviction must rest on the strength of the admissible evidence of the prosecution, not on the weakness or insufficiency of the defense."
