A shooting at a home in Gilbert, Ariz., left five people dead, including the gunman, who killed himself. Jason “J.T.” Ready, a reputed neo-Nazi, has been identified as the shooter. Ready had recently launched a militia movement to patrol the border. A victim, Amber Mederos, was connected to one of Ready’s organizations. The other victims included Mederos’s boyfriend, her 18-month-old daughter, and her mother. At least one person survived the shooting and is currently being treated at a local hospital. A police spokesman said, “This is a domestic situation. We do have a witness that our investigators are interviewing."
