Summary:Eight cases are presented where polygraph tests were given to persons suspected of murdering their own children (three persons) or parents (five persons). The polygraph tests showed no connection of the suspects to the homicide with which they were charged. This was later confirmed by other evidence. The analysis of the polygraph charts of the eight tested persons shows that the opponents of the polygraph are mistaken when they claim that an innocent person will react to the relevant questions. The ethical aspect of these cases was emphasized because the polygraph tests enabled the "clearing" of the innocent persons of these serious accusations, which contributed to implementing justice. The polygraph should be assessed in positive, rather than negative, terms. [PUBLICATION ABSTRACT]
