It’s been a year and a half since a deadly mass shooting in San Bernardino, California. The two attackers were killed after they gunned down 14 people. Georgia native Shannon Johnson, a graduate of Macon’s Windsor Academy, was one of them. He died shielding a co-worker in the attack. Friends of the family say Johnson’s heroics were also in his DNA. His father died years earlier trying to save a co-worker during a factory accident. We talked with Shannon’s brother, Rob, about the family’s heroic legacy.
So, what exactly makes a hero? Do genetics really play a role? We talked with professor Zeno Franco of the Medical College of Wisconsin.
