Wolf was at an apartment complex in Grapevine, roughly 25 miles northwest of Dallas, helping a friend move, Grapevine police told the Fort Worth Star-Telegram.
He was walking downstairs from the building's third floor when he reportedly tried to slide down the handrail. He slipped, and fell down onto concrete, according to the news outlet.
Wolf died from multiple blunt force injuries after the fall, officials said. His death was ruled an accident.
