In 2008, educator and artist, Carol Kennedy, was brutally beaten in her home outside Prescott, Ariz. Carol's ex-husband, stockbroker Steven DeMocker, became the chief suspect when police discovered he was struggling financially and had a toxic relationship with his ex-wife. DeMocker was arrested but court delays and the death of a judge would prolong the case for five years. DeMocker’s girlfriend, Renee Girard, then revealed critical information about his activities after Carol's death. “48 Hours" correspondent Maureen Maher reports.
