In this episode of Law 401: Legal Issues Decoded, hosts Nicole and Michael dive deep into the high-profile Massachusetts trial of Lindsay Clancy, who allegedly killed her three children while suffering from severe mental illness. Joining the conversation is Roger Williams University School of Law criminal law professor and former public defender Shannon Heery.
