Thank you for the correction. Killing his Grandmother is even worse. He might not have actually murdered her but I believe that he did “pull the plug.” You have the reason, the truth.
Was a plug pulled, or did she perhaps have do-not-resuscitate orders of her own. My mother and my late husband were both insistent that heroic efforts not be made to extend their lives when near death. They both had legal documents prepared on the subject.
