In the sweat of an autumn night in November 1974, Ronald DeFeo gunned down his entire family -- father Ronald Sr., mother Louise, brothers Marc and John, and sisters Allison and Dawn as they slept. Within 48 hours, DeFeo had been arrested and was convicted the following year of the mass murder. Today, DeFeo remains incarcerated at Green Haven Correctional Facility in upstate New York. Shattered Hopes initially explores the "official" widely accepted account of the murders while conducting an extensive forensic analysis of the case which clearly suggests that DeFeo could not have committed the crime alone. For nearly four decades, DeFeo has maintained that his sister and another party played a role in the events that transpired at 112 Ocean Avenue. Now, for the first time ever, Shattered Hopes strips away the hazy of mystery behind the infamous Dutch Colonial home and investigates those claims. Pairing vivid reenactments of life in the DeFeo home with extensive and often exclusive interviews by those connected to the case, Shattered takes the viewer on a tour-de-force investigation led by those who knew the family, the officers who investigated the case, and countless others who reveal new information never before revealed.
