We follow up the interview with the shooter’s brother Bruce Paddock with a deeper look inside the mental issues in the family. Dr. James Fallon is a famous neuroscientist who wrote an incredible book about the brain of a psychopath and the nature and nurture combination that can create one. He provides a haunting look into the mind of Stephen Paddock and gives an eerily compelling explanation for why he did what he did. We also talk to former FBI Special Agent Chris Quick, who led the Dylann Roof white supremacist shooting in Charleston, SC investigation, who provides expert analysis on the status of the FBI investigation, now six months old but with still yet up to another six months to go.
