NEW: Prosecutors argue they've proven beyond a reasonable doubt that Lindsay Clancy knew her actions when she killed her children were wrong and could control them, pointing to evidence of planning, her behavior before the killings, and the absence of documented signs of psychosis. They also challenge her claim that she heard a male voice, citing inconsistencies in her account and expert testimony about how unusual such an isolated hallucination would be. Jurors must now determine whether Clancy was legally responsible for her actions. @​BryanLlenas ▻
