A popular chef instructor at a culinary school in Oregon is found shot dead in the campus kitchen. Police think it’s a homicide but have trouble establishing a motive. There are intriguing similarities between the gun that killed Chef Brophy and one belonging to their prime suspect, but they are not the same weapon. On this episode of Bad People, Dr Julia Shaw and Sofie Hagen ask what we really know about the increasing concern surrounding unregistered firearms or “ghost guns”. Can deadly weapons really be manufactured on 3D printers, who is supplying them and do they make it easier to get away with murder?
