New Jersey police made a horrific discovery inside a multimillion dollar mansion: three members of the same family, all fatally shot. But police now believe it was the father, 61-year-old insurance executive David Grodnick who shot and killed his 62-year-old wife, Lora and their 24-year-old daughter, Sloane before turning the gun on himself. We discuss the details of this case, one that follows a disturbing trend this year, where seemingly successful, educated men murder their entire families before killing themselves, with little to no explanation.
