ANDREW WIND A barn that collapsed Friday, killing an Iowa father and his young son, had been moved and installed on a concrete pad the day before, according to a friend of the family. Andy Kaufman, 40, and his 9-year-old son, Beckett, were killed in the 6:30 p.m. collapse on the familyâs rural Cedar Falls, Iowa, property at 9702 Viking Road. âThey moved it from a different location,â said neighbor Trey Nuss, who described Andy as his best friend. âIt was in their yard for a month or so on a trailer.â He helped pour cement âa couple weeksâ ago for the concrete pad where the barn was placed Thursday on the west side of the property near the familyâs house. Renovation work was planned before it would be used to house animals.
