The Lindsay Clancy trial is entering its final phase.  Jurors will hear closing arguments and legal instructions today before beginning deliberations. 

Clancy admits to strangling her three children, but pleaded not guilty to three counts of first-degree murder. 

Prosecutors allege the killings were premeditated, while the defense says Clancy suffered a postpartum psychotic break.  Jurors may consider murder, manslaughter or not guilty verdicts based on a lack of criminal responsibility.
