Steve Berger was in Las Vegas celebrating his 44th birthday, which was Saturday, when he was killed in the attack at the Route 91 Harvest music festival Sunday. Steve Berger was betting on the Wisconsin-Northwestern football game the last time his father, Richard, spoke with him. The Wisconsin native had always been a Badgers fan. “I said ‘Steve, be careful,’” Richard Berger said Tuesday. “That’s the last time I ever talked to him.” “He was so devoted to his family and his children,” Berger said. Steve Berger loved to work, his father said, but was an avid fisherman.
