The family of a man killed after falling from the upper deck of Turner Field last year has sued the Atlanta Braves, parent company Liberty Media Corp. and Major League Baseball Enterprises, alleging the defendants knew the guard rail height was—and still is—dangerously low.

Gregory Kent Murrey, a passionate Braves fan, was watching his hometown team play the New York Yankees last August 29, when he stood up in front of his second-row seat in the upper deck. The height of the guard rail—30 inches above the first row—barely came above his ankles, the suit said. When he lost his balance, there was nothing to stop his fall. He plunged 50 feet and died there, according to the complaint.
